What's new in Sudo 1.9.12
* Fixed a bug in the ptrace-based intercept mode where the current
working directory could include garbage at the end.
* Fixed a compilation error on systems that lack the stdint.h
header.
* Fixed a bug when logging the command's exit status in intercept
mode. The wrong command could be logged with the exit status.
* For ptrace-based intercept mode, sudo will now attempt to
verify that the command path name, arguments and environment
have not changed from the time when they were authorized by the
security policy. The new "intercept_verify" sudoers setting can
be used to control this behavior.
* Fixed running commands with a relative path (e.g. ./foo) in
intercept mode. Previously, this would fail if sudo's current
working directory was different from that of the command.
* Sudo now supports passing the execve(2) system call the NULL
pointer for the `argv` and/or `envp` arguments when in intercept
mode. Linux treats a NULL pointer like an empty array.
* The sudoers LDAP schema now allows sudoUser, sudoRunasUser and
sudoRunasGroup to include UTF-8 characters, not just 7-bit ASCII.
* Fixed a problem with "sudo -i" on SELinux when the target user's
home directory is not searchable by sudo.
* Neovim has been added to the list of visudo editors that support
passing the line number on the command line.
* Fixed a bug in sudo's SHA384 and SHA512 message digest padding.
* Added a new "-N" (--no-update) command line option to sudo which
can be used to prevent sudo from updating the user's cached
credentials. It is now possible to determine whether or not a
user's cached credentials are currently valid by running:
$ sudo -Nnv
and checking the exit value. One use case for this is to indicate
in a shell prompt that sudo is "active" for the user.
* PAM approval modules are no longer invoked when running sub-commands
in intercept mode unless the "intercept_authenticate" option is set.
There is a substantial performance penalty for calling into PAM
for each command run. PAM approval modules are still called for
the initial command.
* Intercept mode on Linux now uses process_vm_readv(2) and
process_vm_writev(2) if available.
* The XDG_CURRENT_DESKTOP environment variable is now preserved
by default. This makes it possible for graphical applications
to choose the correct theme when run via sudo.
* On 64-bit systems, if sudo fails to load a sudoers group plugin,
it will use system-specific heuristics to try to locate a 64-bit
version of the plugin.
* The cvtsudoers manual now documents the JSON and CSV output
formats.
* Fixed a bug where sub-commands were not being logged to a remote
log server when log_subcmds was enabled.
* The new log_stdin, log_stdout, log_stderr, log_ttyin, and log_ttyout
sudoers settings can be used to support more fine-grained I/O logging.
The sudo front-end no longer allocates a pseudo-terminal when running
a command if the I/O logging plugin requests logging of stdin, stdout,
or stderr but not terminal input/output.
* Quieted a libgcrypt run-time initialization warning.
* Fixed a bug in visudo that caused literal backslashes to be removed
from the EDITOR environment variable.
* The sudo Python plugin now implements the "find_spec" method instead
of the the deprecated "find_module". This fixes a test failure when
a newer version of setuptools that doesn't include "find_module" is
found on the system.
* Fixed a bug introduced in sudo 1.9.9 where sudo_logsrvd created
the process ID file, usually /var/run/sudo/sudo_logsrvd.pid, as
a directory instead of a plain file. The same bug could result
in I/O log directories that end in six or more X's being created
literally in addition to the name being used as a template for
the mkdtemp(3) function.
* Fixed a long-standing bug where a sudoers rule with a command
line argument of "", which indicates the command may be run with
no arguments, would also match a literal "" on the command line.
* Added the -I option to visudo which only edits the main sudoers
file. Include files are not edited unless a syntax error is found.
* Fixed "sudo -l -U otheruser" output when the runas list is empty.
Previously, sudo would list the invoking user instead of the
list user.
* Fixed the display of command tags and options in "sudo -l" output
when the RunAs user or group changes. A new line is started for
RunAs changes which means we need to display the command tags
and options again.
* The sesh helper program now uses getopt_long(3) to parse the
command line options.
* The embedded copy of zlib has been updated to version 1.2.13.
* Fixed a bug that prevented event log data from being sent to the
log server when I/O logging was not enabled. This only affected
systems without PAM or configurations where the pam_session and
pam_setcred options were disabled in the sudoers file.
* Fixed a bug where "sudo -l" output included a carriage return
after the newline. This is only needed when displaying to a
terminal in raw mode.
