What's new in Sudo 1.7.10p8?
* Sudo's exit code now indicates a failure if the user does not
successfully authenticate.
* On HP-UX systems, sudo will now use the pstat() function to
determine the tty instead of ttyname().
* Fixed compilation when --without-iologdir configure option is
specified.
* On systems with BSD login classes, if the user specified a group
(not a user) to run the command as, it was possible to specify
a different login class even when the command was not run as the
super user.
* The closefrom() emulation on Mac OS X now uses /dev/fd if possible.
It also now sets the close on exec flag instead of actually
closing the descriptors to avoid a crash in libdispatch.
* The sudoers plugin will now ignore invalid domain names when
checking netgroup membership. Most Linux systems use the string
"(none)" for the NIS-style domain name instead of an empty string.
* Fixed the logic when checking environment variables on the
command line against the env_check and env_delete blacklists.
This is only a problem when env_reset is disabled in sudoers.
What's new in Sudo 1.7.10p7?
* A time stamp file with the date set to the epoch by "sudo -k"
is now completely ignored regardless of what the local clock is
set to. Previously, if the local clock was set to a value between
the epoch and the time stamp timeout value, a time stamp reset
by "sudo -k" would be considered current.
What's new in Sudo 1.7.10p6?
* The tty-specific time stamp file now includes the session ID
of the sudo process that created it. If a process with the same
tty but a different session ID runs sudo, the user will now be
prompted for a password (assuming authentication is required for
the command).
What's new in Sudo 1.7.10p5?
* On systems where the controlling tty can be determined via /proc
or sysctl(), sudo will no longer fall back to using ttyname()
if the process has no controlling tty. This prevents sudo from
using a non-controlling tty for logging and time stamp purposes.
What's new in Sudo 1.7.10?
* If the user is a member of the "exempt" group in sudoers, they
will no longer be prompted for a password even if the -k flag
is specified with the command. This makes "sudo -k command"
consistent with the behavior one would get if the user ran "sudo
-k" immediately before running the command.
* The sudoers file may now be a symbolic link. Previously, sudo
would refuse to read sudoers unless it was a regular file.
* The user/group/mode checks on sudoers files have been relaxed.
As long as the file is owned by the sudoers uid, not world-writable
and not writable by a group other than the sudoers gid, the file
is considered OK. Note that visudo will still set the mode to
the value specified at configure time.
* /etc/environment is no longer read directly on Linux systems
when PAM is used. Sudo now merges the PAM environment into the
user's environment which is typically set by the pam_env module.
* The initial evironment created when env_reset is in effect now
includes the contents of /etc/environment on AIX systems and the
"setenv" and "path" entries from /etc/login.conf on BSD systems.
* On systems with an SVR4-style /proc file system, the /proc/pid/psinfo
file is now uses to determine the controlling terminal, if possible.
This allows tty-based tickets to work properly even when, e.g.
standard input, output and error are redirected to /dev/null.
* The sudoreplay command can now properly replay sessions where
no tty was present.
* Fixed a race condition that could cause sudo to receive SIGTTOU
(and stop) when resuming a shell that was run via sudo when I/O
logging (and use_pty) is not enabled.
Fix seuciry problem of CVE-2012-2337.
What's new in Sudo 1.7.9p1?
* Fixed a bug when matching against an IP address with an associated
netmask in the sudoers file. In certain circumstances, this
could allow users to run commands on hosts they are not authorized
for.
What's new in Sudo 1.7.9?
* Fixed a false positive in visudo strict mode when aliases are
in use.
* The line on which a syntax error is reported in the sudoers file
is now more accurate. Previously it was often off by a line.
* The #include and #includedir directives in sudoers now support
relative paths. If the path is not fully qualified it is expected
to be located in the same directory of the sudoers file that is
including it.
* visudo will now fix the mode on the sudoers file even if no changes
are made unless the -f option is specified.
* The "use_loginclass" sudoers option works properly again.
* For LDAP-based sudoers, values in the search expression are now
escaped as per RFC 4515.
* Fixed a race condition when I/O logging is not enabled that could
result in tty-generated signals (e.g. control-C) being received
by the command twice.
* If none of the standard input, output or error are connected to
a tty device, sudo will now check its parent's standard input,
output or error for the tty name on systems with /proc and BSD
systems that support the KERN_PROC_PID sysctl. This allows
tty-based tickets to work properly even when, e.g. standard
input, output and error are redirected to /dev/null.
* Fixed a bug where a pattern like "/usr/*" included /usr/bin/ in
the results, which would be incorrectly be interpreted as if the
sudoers file had specified a directory.
* "visudo -c" will now list any include files that were checked
in addition to the main sudoers file when everything parses OK.
* Users that only have read-only access to the sudoers file may
now run "visudo -c". Previously, write permissions were required
even though no writing is down in check-only mode.
What's new in Sudo 1.7.8p2?
* Fixed a crash in the monitor process on Solaris when NOPASSWD
was specified or when authentication was disabled.
What's new in Sudo 1.7.6p2
* Two-character CIDR-style IPv4 netmasks are now matched correctly
in the sudoers file.
* A build error with MIT Kerberos V has been resolved.
What's new in Sudo 1.7.6p1
* A non-existent includedir is now treated the same as an empty
directory and not reported as an error.
* Removed extraneous parens in LDAP filter when sudoers_search_filter
is enabled that can cause an LDAP search error.
* pkgsrc change: trying to use user-destdir.
What's new in Sudo 1.7.5?
* When using visudo in check mode, a file named "-" may be used to
check sudoers data on the standard input.
* Sudo now only fetches shadow password entries when using the
password database directly for authentication.
* Password and group entries are now cached using the same key
that was used to look them up. This fixes a problem when looking
up entries by name if the name in the retrieved entry does not
match the name used to look it up. This may happen on some systems
that do case insensitive lookups or that truncate long names.
* GCC will no longer display warnings on glibc systems that use
the warn_unused_result attribute for write(2) and other system calls.
* If a PAM account management module denies access, sudo now prints
a more useful error message and stops trying to validate the user.
* Fixed a potential hang on idle systems when the sudo-run process
exits immediately.
* Sudo now includes a copy of zlib that will be used on systems
that do not have zlib installed.
* The --with-umask-override configure flag has been added to enable
the "umask_override" sudoers Defaults option at build time.
* Sudo now unblocks all signals on startup to avoid problems caused
by the parent process changing the default signal mask.
* LDAP Sudoers entries may now specify a time period for which
the entry is valid. This requires an updated sudoers schema
that includes the sudoNotBefore and sudoNotAfter attributes.
Support for timed entries must be explicitly enabled in the
ldap.conf file. Based on changes from Andreas Mueller.
* LDAP Sudoers entries may now specify a sudoOrder attribute that
determines the order in which matching entries are applied. The
last matching entry is used, just like file-based sudoers. This
requires an updated sudoers schema that includes the sudOrder
attribute. Based on changes from Andreas Mueller.
* When run as sudoedit, or when given the -e flag, sudo now treats
command line arguments as pathnames. This means that slashes
in the sudoers file entry must explicitly match slashes in
the command line arguments. As a result, and entry such as:
user ALL = sudoedit /etc/*
will allow editing of /etc/motd but not /etc/security/default.
* NETWORK_TIMEOUT is now an alias for BIND_TIMELIMIT in ldap.conf for
compatibility with OpenLDAP configuration files.
* The LDAP API TIMEOUT parameter is now honored in ldap.conf.
* The I/O log directory may now be specified in the sudoers file.
* Sudo will no longer refuse to run if the sudoers file is writable
by root.
* Sudo now performs command line escaping for "sudo -s" and "sudo -i"
after validating the command so the sudoers entries do not need
to include the backslashes.
* Logging and email sending are now done in the locale specified
by the "sudoers_locale" setting ("C" by default). Email send by
sudo now includes MIME headers when "sudoers_locale" is not "C".
* The configure script has a new option, --disable-env-reset, to
allow one to change the default for the sudoers Default setting
"env_reset" at compile time.
* When logging "sudo -l command", sudo will now prepend "list "
to the command in the log line to distinguish between an
actual command invocation in the logs.
* Double-quoted group and user names may now include escaped double
quotes as part of the name. Previously this was a parse error.
* Sudo once again restores the state of the signal handlers it
modifies before executing the command. This allows sudo to be
used with the nohup command.
* Resuming a suspended shell now works properly when I/O logging
is not enabled (the I/O logging case was already correct).
* Install README.LDAP when "ldap" is enabled in PKG_OPTIONS.
* Fix build problem when "kerberos" is enabled in PKG_OPTIONS.
Bump PKGREVISION since default PLIST has changed.
relevant bugs) version:
Major changes between version 1.7.4p3 and 1.7.4p4:
* A potential security issue has been fixed with respect to the
handling of sudo's -g command line option when -u is also
specified. The flaw may allow an attacker to run commands as a
user that is not authorized by the sudoers file.
* A bug has been fixed where "sudo -l" output was incomplete if
multiple sudoers sources were defined in nsswitch.conf and there
was an error querying one of the sources.
* The log_input, log_output, and use_pty sudoers options now work
correctly on AIX. Previously, sudo would hang if they were
enabled.
* Fixed "make install" when sudo is built in a directory other
than the directory that holds the sources.
* The runas_default sudoers setting now works properly in a
per-command Defaults line.
* Suspending and resuming the bash shell when PAM is in use now
works properly. The SIGCONT signal was not being propagated to
the child process.
Major changes between version 1.7.4p2 and 1.7.4p3:
* A bug has been fixed where duplicate HOME environment variables
could be set when the env_reset setting was disabled and the
always_set_home setting was enabled in sudoers.
* The value of sysconfdir is now substituted into the path to the
sudoers.d directory in the installed sudoers file.
* Fixed compilation problems on Irix and other platforms.
* If multiple PAM "auth" actions are specified and the user enters
^C at the password prompt, sudo will now abort any subsequent
"auth" actions. Previously it was necessary to enter ^C once for
each "auth" action.
Major changes between version 1.7.4p1 and 1.7.4p2:
* Fixed a bug where sudo could spin in a cpu loop waiting for the
child process.
* Packaging fixes for sudo.pp to better handle patchlevels.
Major changes between version 1.7.4 and 1.7.4p1:
* Fix a bug introduced in sudo 1.7.3 that prevented the -k and -K
options from functioning when the tty_tickets sudoers option was
enabled.
* Sudo no longer prints a warning when the -k or -K options are
specified and the ticket file does not exist.
* Changes to the configure script to enable cross-compilation of
Sudo.
Major changes between version 1.7.3 and 1.7.4:
* Sudoedit will now preserve the file extension in the name of the
temporary file being edited. The extension is used by some
editors (such as emacs) to choose the editing mode.
* Time stamp files have moved from /var/run/sudo to either
/var/db/sudo, /var/lib/sudo or /var/adm/sudo. The directories
are checked for existence in that order. This prevents users
from receiving the sudo lecture every time the system reboots.
Time stamp files older than the boot time are ignored on systems
where it is possible to determine this.
* Ancillary documentation (README files, LICENSE, etc) is now
installed in a sudo documentation directory.
* Sudo now recognizes "tls_cacert" as an alias for "tls_cacertfile"
in ldap.conf.
* Defaults settings that are tied to a user, host or command may
now include the negation operator. For example:
Defaults:!millert lecture
will match any user but millert.
* The default PATH environment variable, used when no PATH variable
exists, now includes /usr/sbin and /sbin.
* Sudo now uses polypkg for cross-platform packing.
* On Linux, sudo will now restore the nproc resource limit before
executing a command, unless the limit appears to have been
modified by pam_limits. This avoids a problem with bash scripts
that open more than 32 descriptors on SuSE Linux, where
sysconf(_SC_CHILD_MAX) will return -1 when RLIMIT_NPROC is set
to RLIMIT_UNLIMITED (-1).
* Visudo will now treat an unrecognized Defaults entry as a parse
error (sudo will warn but still run).
* The HOME and MAIL environment variables are now reset based on
the target user's password database entry when the env_reset
sudoers option is enabled (which is the case in the default
configuration). Users wishing to preserve the original values
should use a sudoers entry like:
Defaults env_keep += HOME
to preserve the old value of HOME and
Defaults env_keep += MAIL
to preserve the old value of MAIL.
* The tty_tickets option is now on by default.
* Fixed a problem in the restoration of the AIX authdb registry
setting.
* If PAM is in use, wait until the process has finished before
closing the PAM session.
* Fixed "sudo -i -u user" where user has no shell listed in the
password database.
* When logging I/O, sudo now handles pty read/write returning ENXIO,
as seen on FreeBSD when the login session has been killed.
* Sudo now performs I/O logging in the C locale. This avoids
locale-related issues when parsing floating point numbers in the
timing file.
* Added support for Ubuntu-style admin flag dot files.
Major changes between version 1.7.2p8 and 1.7.3:
* Support for logging a command's input and output as well as the
ability to replay sessions. For more information, see the
documentation for the log_input and log_output Defaults options
in the sudoers manual. Also see the sudoreplay manual for
information on replaying I/O log sessions.
* The use_pty sudoers option can be used to force a command to be
run in a pseudo-pty, even when I/O logging is not enabled.
* On some systems, sudo can now detect when a user has logged out
and back in again when tty-based time stamps are in use.
Supported systems include Solaris systems with the devices file
system, Mac OS X, and Linux systems with the devpts filesystem
(pseudo-ttys only).
* On AIX systems, the registry setting in /etc/security/user is
now taken into account when looking up users and groups.
Sudo now applies the correct the user and group ids when running
a command as a user whose account details come from a different
source (e.g. LDAP or DCE vs. local files).
* Support for multiple sudoers_base and uri entries in ldap.conf.
When multiple entries are listed, sudo will try each one in the
order in which they are specified.
* Sudo's SELinux support should now function correctly when running
commands as a non-root user and when one of stdin, stdout or stderr
is not a terminal.
* Sudo will now use the Linux audit system with configure with the
--with-linux-audit flag.
* Sudo now uses mbr_check_membership() on systems that support it
to determine group membership. Currently, only Darwin (Mac OS X)
supports this.
* When the tty_tickets sudoers option is enabled but there is no
terminal device, sudo will no longer use or create a tty-based
ticket file. Previously, sudo would use a tty name of "unknown".
As a consequence, if a user has no terminal device, sudo will now
always prompt for a password.
* The passwd_timeout and timestamp_timeout options may now be
specified as floating point numbers for more granular timeout
values.
* Negating the fqdn option in sudoers now works correctly when sudo
is configured with the --with-fqdn option. In previous versions
of sudo the fqdn was set before sudoers was parsed.
Major changes between sudo 1.7.2p7 and 1.7.2p8:
* Fixed a crash on AIX when LDAP support is in use.
* Fixed problems with the QAS non-Unix group support
Sudo versions 1.7.2p6 and 1.6.9p22 are now available. These releases
fix a privilege escalation bug in the sudoedit functionality.
Summary:
A flaw exists in sudo's -e option (aka sudoedit) in sudo versions
1.6.8 through 1.7.2p5 that may give a user with permission to
run sudoedit the ability to run arbitrary commands. This bug
is related to, but distinct from, CVE 2010-0426.
Sudo versions affected:
1.6.8 through 1.7.2p5 inclusive.
Major changes between sudo 1.7.2p1 and 1.7.2p2:
* Fixed a a bug where the negation operator in a Cmnd_List
was not being honored.
* Sudo no longer produces a parse error when #includedir references
a directory that contains no valid filenames.
* The sudo.man.pl and sudoers.man.pl files are now included in
the distribution for people who wish to regenerate the man pages.
* Fixed the emulation of krb5_get_init_creds_opt_alloc() for MIT kerberos.
* When authenticating via PAM, set PAM_RUSER and PAM_RHOST early so
they can be used during authentication.
Changes in 1.7.2p1 since 1.7.2:
===============================
* Fixed the expansion of the %h escape in #include file names introduced in
sudo 1.7.1.
Changes in 1.7.2 since 1.7.1:
=============================
* A new #includedir directive is available in sudoers. This can be used to
implement an /etc/sudo.d directory. Files in an includedir are not edited
by visudo unless they contain a syntax error.
* The -g option did not work properly when only setting the group (and not
the user). Also, in -l mode the wrong user was displayed for sudoers
entries where only the group was allowed to be set.
* Fixed a problem with the alias checking in visudo which could prevent
visudo from exiting.
* Sudo will now correctly parse the shell-style /etc/environment file format
used by pam_env on Linux.
* When doing password and group database lookups, sudo will only cache an
entry by name or by id, depending on how the entry was looked up.
Previously, sudo would cache by both name and id from a single lookup, but
this breaks sites that have multiple password or group database names that
map to the same uid or gid.
* User and group names in sudoers may now be enclosed in double quotes to
avoid having to escape special characters.
* BSM audit fixes when changing to a non-root uid.
* Experimental non-Unix group support. Currently only works with Quest
Authorization Services and allows Active Directory groups fixes for
Minix-3.
* For Netscape/Mozilla-derived LDAP SDKs the certificate and key paths may
be specified as a directory or a file. However, version 5.0 of the SDK
only appears to support using a directory (despite documentation to the
contrary). If SSL client initialization fails and the certificate or key
paths look like they could be default file name, strip off the last path
element and try again.
* A setenv() compatibility fix for Linux systems, where a NULL value is
treated the same as an empty string and the variable name is checked
against the NULL pointer.
pkgsrc change: add LICENSE.
What's new in Sudo 1.7.1?
* A new Defaults option "pwfeedback" will cause sudo to provide visual
feedback when the user is entering a password.
* A new Defaults option "fast_glob" will cause sudo to use the fnmatch()
function for file name globbing instead of glob(). When this option
is enabled, sudo will not check the file system when expanding wildcards.
This is faster but a side effect is that relative paths with wildcard
will no longer work.
* New BSM audit support for systems that support it such as FreeBSD
and Mac OS X.
* The file name specified with the #include directive may now include
a %h escape which is expanded to the short form of hostname.
* The -k flag may now be specified along with a command, causing the
user's timestamp file to be ignored.
* New support for Tivoli-based LDAP START_TLS, present in AIX.
* New support for /etc/netsvc.conf on AIX.
* The unused alias checks in visudo now handle the case of an alias
referring to another alias.
* pkgsrc change: relax restriction to kerberos package.
What's new in Sudo 1.7.0?
* Rewritten parser that converts sudoers into a set of data structures.
This eliminates a number of ordering issues and makes it possible to
apply sudoers Defaults entries before searching for the command.
It also adds support for per-command Defaults specifications.
* Sudoers now supports a #include facility to allow the inclusion of other
sudoers-format files.
* Sudo's -l (list) flag has been enhanced:
o applicable Defaults options are now listed
o a command argument can be specified for testing whether a user
may run a specific command.
o a new -U flag can be used in conjunction with "sudo -l" to allow
root (or a user with "sudo ALL") list another user's privileges.
* A new -g flag has been added to allow the user to specify a
primary group to run the command as. The sudoers syntax has been
extended to include a group section in the Runas specification.
* A uid may now be used anywhere a username is valid.
* The "secure_path" run-time Defaults option has been restored.
* Password and group data is now cached for fast lookups.
* The file descriptor at which sudo starts closing all open files is now
configurable via sudoers and, optionally, the command line.
* Visudo will now warn about aliases that are defined but not used.
* The -i and -s command line flags now take an optional command
to be run via the shell. Previously, the argument was passed
to the shell as a script to run.
* Improved LDAP support. SASL authentication may now be used in
conjunction when connecting to an LDAP server. The krb5_ccname
parameter in ldap.conf may be used to enable Kerberos.
* Support for /etc/nsswitch.conf. LDAP users may now use nsswitch.conf
to specify the sudoers order. E.g.:
sudoers: ldap files
to check LDAP, then /etc/sudoers. The default is "files", even
when LDAP support is compiled in. This differs from sudo 1.6
where LDAP was always consulted first.
* Support for /etc/environment on AIX and Linux. If sudo is run
with the -i flag, the contents of /etc/environment are used to
populate the new environment that is passed to the command being
run.
* If no terminal is available or if the new -A flag is specified,
sudo will use a helper program to read the password if one is
configured. Typically, this is a graphical password prompter
such as ssh-askpass.
* A new Defaults option, "mailfrom" that sets the value of the
"From:" field in the warning/error mail. If unspecified, the
login name of the invoking user is used.
* A new Defaults option, "env_file" that refers to a file containing
environment variables to be set in the command being run.
* A new flag, -n, may be used to indicate that sudo should not
prompt the user for a password and, instead, exit with an error
if authentication is required.
* If sudo needs to prompt for a password and it is unable to disable
echo (and no askpass program is defined), it will refuse to run
unless the "visiblepw" Defaults option has been specified.
* Prior to version 1.7.0, hitting enter/return at the Password: prompt
would exit sudo. In sudo 1.7.0 and beyond, this is treated as
an empty password. To exit sudo, the user must press ^C or ^D
at the prompt.
* visudo will now check the sudoers file owner and mode in -c (check)
mode when the -s (strict) flag is specified.
653) Fixed installation of sudo_noexec.so on AIX.
654) Updated libtool to version 1.5.26.
655) Fixed printing of default SELinux role and type in -V mode.
656) The HOME environment variable is once again preserved by default,
as per the documentation.
pkgsrc changes:
- Explict to depends security/heimdal package when kerberos option is
specified. PR pkg/37999 should be fixed.
Change:
646) Sudo will now set the nproc resource limit to unlimited on Linux
systems to work around Linux's setuid() resource limit semantics.
On PAM systems the resource limits will be reset by pam_limits.so
before the command is executed.
647) SELinux support that can be used to implement role based access
control (RBAC). A role and (optional) type may be specified
in sudoers or on the command line. These are then used in the
security context that the command is run as.
648) Fixed a Kerberos 5 compilation problem with MIT Kerberos.
Sudo 1.6.9p13 released.
649) Fixed an invalid assumption in the PAM conversation function
introduced in version 1.6.9p9. The conversation function may
be called for non-password reading purposes as well.
650) Fixed freeing an uninitialized pointer in -l mode, introduced in
version 1.6.9p13.
651) Check /etc/sudoers after LDAP even if the user was found in LDAP.
This allows Defaults options in /etc/sudoers to take effect.
652) Add missing checks for enforcing mode in SELinux RBAC mode.
Sudo 1.6.9p14 released.
pkgsrc change: added DESTDIR support.
Major changes since Sudo 1.6.9p6:
o Reverted back to to using TCSAFLUSH instead of TCSADRAIN when
turning off echo during password reading.
o Fixed a configure bug that was preventing the addition of -lutil for
login.conf support on FreeBSD and NetBSD.
o Added a configure check for struct in6_addr since some systems
define AF_INET6 but have no real IPv6 support.
617) Fixed a bug in the IP address matching introduced by the IPV6 merge.
618) For "visudo -f file" we now use the permissions of the original file
and not the hard-coded sudoers owner/group/mode. This makes
it possible to use visudo with a revision control system.
619) Fixed sudoedit when used on a non-existent file.
620) Regenerated configure using autoconf 2.6.1 and libtool 1.5.24.
621) Groups and netgroups are now valid in an LDAP sudoRunas statement.
pkgsrc change:
Make these options mutual exclusive: kerberos pam skey.
(Really, combinations of kerberos and pam, pam and skey are conflicts.)
CHANGES:
609) Worked around a bug ins some PAM implementations that caused a crash
when no tty was present.
610) Fixed a crash on some platforms in the error logging function.
611) Documentation improvements.
Sudo 1.6.9p1 released.
612) Fixed updating of the saved environment when the environ pointer
gets changed out from underneath us.
Sudo 1.6.9p2 released.
613) Fixed a bug related to supplemental group matching introduced
in 1.6.9.
Sudo 1.6.9p3 released.
614) Added IPv6 support from YOSHIFUJI Hideaki.
615) Fixed sudo_noexec installation path.
616) Fixed a K&R compilation error.
Sudo 1.6.9p4 released.
(in fact, it's not clear that there is a good way to do so). The resulting
configuration works fine *except* if it encounters a host that has 3DES
but no DES service keys in its keytab.
Fix this by explicitly passing 0 ("default enctype") to Kerberos.
install script. The latter are special install-sh script options that
check whether the invoking user is the root user or not, which is
completely unnecessary.
cleanse environment of variables that alter behavior of Kerberos library
so the user can't override the default keytab location, and do *not*
ignore missing keytab errors. Prevents root compromise via spoofed KDC
on systems with Kerberos libraries but no host key in keytab, no keytab,
or keytab overidden via environment.
Don't insist that the keytab key be DES -- some Kerberos sites are 3DES/AES
only.
Somewhat less invasive than the fix Todd incorporated into the 1.6.9 branch
of sudo (presently beta) but equivalent (though not as clean).

Major changes since Sudo 1.6.8:
o Sudoedit now re-opens the temp file as the invoking user
and will only open regular files.
o Better detection of unchanged files in sudoedit.
o The path to ldap.conf is now configurable.
o Added SSL tls_* certificate checking options when using LDAP.
o The sample pam config file has been updated.
adds two new options, ldap and pam.
Changes:
* Sudo now supports storing sudoers info in LDAP (optionally using TLS).
* There is a new -e option to edit files the with uid of the invoking
user. This makes it possible to give users to ability to safely edit
files without the possibility of editing other files or running commands
as the target user. If sudo is run as "sudoedit" the -e flag is implied.
* A new tag, NOEXEC, will prevent a dynamically-linked program being run
by sudo from executing another program (think shell escapes). Because
this uses LD_PRELOAD it has no effect on static binaries.
* A uid specified in sudoers now matches the user specified by the -u flag
even if the -u flag specified a name, not a uid.
* Added a -i option to simulate an initial login similar to "su -".
* If sudo is used to run as root shell, further sudo commands will be logged
as run by the user specified by the SUDO_USER environment variable. In -e
mode (sudoedit), SUDO_USER is used to determine what user to run the editor
when the real uid is 0.
* The sudoers file is now parsed as the runas user in all cases instead of
root. This fixes some issues with running NFS-mounted commands.
* If the target user == invoking user a password is no longer required.
* Sudo now produces a sensible error message when the targetpw Defaults option
is set and a non-existent uid is specified via the -u option.
* A negated user/uid in a runas list is now treated the same as a negated
command and overrides a previously allowed entry.
* PAM support now uses Use pam_acct_mgmt() to check for disabled accounts.
* Added a check in visudo for runas_default being used before it was set.
* Fixed several issues when closing all open descriptors. Sudo now uses
closefrom() if it exists, otherwise it uses /proc/$$/fd if that exists
with a fallback of closing all possible descriptors.
* Quoting globbing characters with a backslash now works as documented.
* Fixed a problem on FreeBSD (and perhaps others) when the user is only
listed in NIS (not master.passwd) and netgroups are used in the
master.passwd file.
* The username in a log entry is no longer truncated at 8 characters.
* Added a "sudo_lecture" option that can point to a file containing a
custom lecture.
* The timeout for password reading is now done via alarm(), not select().
* /tmp/.odus is no longer used for timestamps by default.
* Sudo now works on the nsr-tandem-nsk platform.
* Fixed the --with-stow configure option.
* TIS fwtk authentication now supports fwtk 2.0 and higher.
* Added Stan Lee / Uncle Ben quote to the lecture from RedHat.
* Added the --with-pc-insults configure to replace politically incorrect
insults with other ones.
509) Fixed a typo that caused a compilation error on Heimdal.
510) Darwin (MacOS X) doesn't have a real setreuid() system call.
511) Fixed a problem with large numbers of environment variables.
478) Wildcards now work correctly in the env_keep Defaults directive.
479) Added support for non-root timestamp dirs. This allows the timestamp
dir to be shared via NFS (though this is not recommended).
480) Removed double printing of bad environment variable table in -V mode.
481) configure script has been regenerated with autoconf 2.5.7.
This required some changes to configure.in.
482) Fixed a compilation problem on SunOS; thanks to Alek O. Komarnitsky.
483) SecurID 5.0 API support from Michael Stroucken.
484) Restore state of signal handlers to what we had upon startup.
Fixes a problem when using sudo with nohup; thanks to Paul Markham.
485) Revamp set_perms() to use setresuid() or setreuid() when available
in preference to POSIX stuff since they allow us to properly
implement "stay_setuid" whereas POSIX does not really.
486) In strict mode sudo did not throw an error for undefined User_Aliases.
487) Fixed a Makefile bug on IRIX.
488) Write the prompt *after* turning off echo to avoid some password
characters being echoed on heavily-loaded machines with fast typists.
489) Added %U and %H escapes in the prompt and fixed treatment of %%.
490) Visudo will now add a final newline to sudoers if the user's editor
not add one before EOF.
491) The lexer state is now reset to its initial value on EOF.
Previously, the state was not reset between parser invocations
which could cause problems for visudo in rare cases.
492) Added support for Defaults that apply based on the RunasUser.
493) Sudo now includes copies of strlc{at,py} and uses them throughout.
494) Sudo is now careful to avoid interger overflow when allocating
memory. This is one of those "should not happen" situations.
495) Added a configure option (--with-stow) to make sudo compatible
with GNU stow.
496) auth/kerb5.c now compiles under Heimdal.
497) The volatile prefix is used in the hopes of preventing compilers
from optimizing away memory zeroing. Unfortunately, this results
in some warnings from gcc.
498) Better Kerberos IV/V support in the configure script.
499) Fixed a logic thinko in the SIGCHLD handler that caused problems
with rlogin on HP-UX.
500) configure now adds -R to LDFLAGS when it adds -L for Solaris and
SVR4. There is a configure option, --with-rpath, to control this.
501) On AIX, configure will pass extra directory paths to the linker
via the -blibpath ld option. This is only active when additional
library paths are used. It may be disabled via the
--without-blibpath configure option.
502) The --with-skey and --with-opie configure options now take
an optional directory argument that should have an include and
lib dir for the skey/opie include file and library respectively.
503) Fixed false positives in the overflow detection of expand_prompt().
Added --disable-root-mailer to CONFIGURE_ARGS better security.
Changes from 1.6.3p7 to 1.6.5 is attached bellow.
417) Visudo now checks for the existence of an editor and gives a sensible
error if it does not exist.
418) The path to the editor for visudo is now a colon-separated list of
allowable editors. If the user has $EDITOR set and it matches
one of the allowed editors that editor will be used. If not,
the first editor that actually exists is used.
419) Visudo now does its own fork/exec instead of calling system(3).
420) Allow special characters (including '#') to be embedded in pathnames
if quoted by a '\\'. The quoted chars will be dealt with by fnmatch().
Unfortunately, 'sudo -l' still prints the '\\'.
421) Added the always_set_home option.
422) Strip NLSPATH and PATH_LOCALE out from the environment to prevent
reading of protected files by a less privileged user.
423) Added support for BSD authentication and associated -a flag.
424) Added check for _innetgr(3) since NCR systems have this instead
of innetgr(3).
425) Added stay_setuid option for systems that have libraries that perform
extra paranoia checks in system libraries for setuid programs.
426) Environment munging is now done by hand. The environment is zeroed
upon sudo startup and a new environment is built before the command
is executed. This means we don't rely on getenv(3), putenv(3),
or setenv(3).
427) Added a class of environment variables that are only cleared if they
contain '/' or '%' characters.
428) Use stashed user_gid when checking against exempt gid since sudo
sets its gid to SUDOERS_GID, making getgid() return that, not the
real gid. Fixes problem with setting exempt group == SUDOERS_GID.
Fix from Paul Kranenburg.
429) Fixed file locking in visudo on NeXT which has a broken lockf().
Patch from twetzel@gwdg.de.
430) Regenerated configure script with autoconf-2.52 (required some
tweaking of configure.in and friends).
431) Added mail_badpass option to send mail when the user does not
authenticate successfully.
432) Added env_reset Defaults option to reset the environment to
a clean slate. Also implemented env_keep Defaults option
to specify variables to be preserved when resetting the
environment.
433) Added env_check and env_delete Defaults options to allow the admin
to modify the builtin list of environment variables to remove.
434) If timestamp_timeout < 0 then the timestamp never expires. This
allows users to manage their own timestamps and create or delete
them via 'sudo -v' and 'sudo -k' respectively.
435) Authentication routines that use sudo's tgetpass() now accept
^C or ^Z at the password prompt and sudo will act appropriately.
436) Added a check-only mode to visudo to check an existing sudoers
file for sanity.
437) Visudo can now edit an alternate sudoers file.
438) If sudo is configured with S/Key support and the system has
skeyaccess(3) use that to determine whether or not to allow
a normal Unix password or just S/Key.
439) Fixed CIDR handling in sudoers.
440) Fixed a segv if the local hostname is not resolvable and
the 'fqdn' option is set.
441) "listpw=never" was not having an effect for users who did not
appear in sudoers--now it does.
442) The --without-sendmail option now works on systems with
a /usr/include/paths.h file that defines _PATH_SENDMAIL.
443) Removed the "secure_path" Defaults option as it does not work and
cannot work until the parser is overhauled.
444) Added new -P flag and "preserve_groups" sudoers option to cause
sudo to preserve the group vector instead of setting it to that
of the target user. Previously, if the target user was root
the group vector was not changed. Now it is always changed unless
the -P flag or "preserve_groups" option was given.
445) If find_path() fails as root, try again as the invoking user (useful
for NFS). Idea from Chip Capelik.
446) Use setpwent()/endpwent() and its shadow equivalents to be sure
the passwd/shadow file gets closed.
447) Use getifaddrs(3) to get the list of network interfaces if it is
available.
448) Dump list of local IP addresses and environment variables to clear
when 'sudo -V' is run as root.
449) Reorganized the lexer a bit and added more states. Sudo now does a
better job of parsing command arguments in the sudoers file.
450) Wrap each call to syslog() with openlog()/closelog() since some
things (such as PAM) may call closelog(3) behind sudo's back.
451) The LOGNAME and USER environment variables are now set if the user
specified a target uid and that uid exists in the password database.
452) configure will no longer add the -g flag to CFLAGS by default.
453) Now call pam_setcreds() to setup creds for the target user when
PAM is in use. On Linux this often sets resource limits.
454) If "make install" is run by non-root and the destination dir
is writable, install things normally but don't set owner and mode.
455) The Makefile now supports installing in a shadow hierarchy
specified via the DESTDIR variable.
456) config.h.in is now generated by autoheader.
Sudo 1.6.4 released.
457) Move the call to rebuild_env() until after MODE_RESET_HOME is set.
Otherwise, the set_home option has no effect.
458) Fix use of freed memory when the "fqdn" flag is set. This was
introduced by the fix for the "segv when gethostbynam() fails" bug.
459) Add 'continue' statements to optimize the switch statement.
From Solar Designer.
Sudo 1.6.4p1 released.
460) Some special characters were not being escaped properly (e..g '\,')
in command line arguments and would cause a syntax error instead.
461) "sudo -l" would not work if the always_set_home option was set.
462) Added a configure option to disable use of POSIX saved IDs for
operating systems where these are broken.
463) The SHELL environment variable was preserved from the user's environment
instead of being reset based on the passwd database even when the
"env_reset" option was set.
Sudo 1.6.4p2 released.
464) Added a configure option to cause mail sent by sudo to be run as
the invoking user instead of root. Some people consider this to
be safer.
465) If the mailer is being run as root, use a hard-coded environment
that is not influenced in any way by the invoking user's environment.
466) Fixed the call to skeyaccess(). Patch from Phillip E. Lobbes.
Sudo 1.6.5 released.
