* NEWS, configure, configure.ac:
Sudo 1.8.20p2
[47836f4c9834]
* src/ttyname.c:
A command name may also contain newline characters so read
/proc/self/stat until EOF. It is not legal for /proc/self/stat to
contain embedded NUL bytes so treat the file as corrupt if we see
any. With help from Qualys.
This is not exploitable due to the /dev traversal changes in sudo
1.8.20p1 (thanks Solar!).

This is a Darwin-ported pinentry, which works natively without
pulling in gtk or qt4 dependencies. It is independent from the
original collection of pinentry tools, and grew its own code and
repository, although it still uses Assuan protocol internally (and
can therefore be integrated with gpg-agent and enigmail under Mac OS).
Note that it uses xcodebuild instead of autotools and generates an App.
I decided to copy over the .app as under libexec and rely on sh script
for invocation, App cannot be called through symlinks.
Description:
This is a collection of simple PIN or passphrase entry dialogs which
utilize the Assuan protocol as described by the aegypten project.
It provides programs for several graphical toolkits, such as GTK+ and
QT, as well as for the console, using curses.
This package is a port of the pinentry tool for Darwin.
Potentially-incompatible changes
================================
This release includes a number of changes that may affect existing
configurations:
* This release deprecates the sshd_config UsePrivilegeSeparation
option, thereby making privilege separation mandatory. Privilege
separation has been on by default for almost 15 years and
sandboxing has been on by default for almost the last five.
* The format of several log messages emitted by the packet code has
changed to include additional information about the user and
their authentication state. Software that monitors ssh/sshd logs
may need to account for these changes. For example:
Connection closed by user x 1.1.1.1 port 1234 [preauth]
Connection closed by authenticating user x 10.1.1.1 port 1234 [preauth]
Connection closed by invalid user x 1.1.1.1 port 1234 [preauth]
Affected messages include connection closure, timeout, remote
disconnection, negotiation failure and some other fatal messages
generated by the packet code.
* [Portable OpenSSH only] This version removes support for building
against OpenSSL versions prior to 1.0.1. OpenSSL stopped supporting
versions prior to 1.0.1 over 12 months ago (i.e. they no longer
receive fixes for security bugs).
Changes since OpenSSH 7.4
=========================
This is a bugfix release.
Security
--------
* ssh(1), sshd(8): Fix weakness in CBC padding oracle countermeasures
that allowed a variant of the attack fixed in OpenSSH 7.3 to proceed.
Note that the OpenSSH client disables CBC ciphers by default, sshd
offers them as lowest-preference options and will remove them by
default entriely in the next release. Reported by Jean Paul
Degabriele, Kenny Paterson, Martin Albrecht and Torben Hansen of
Royal Holloway, University of London.
* sftp-client(1): [portable OpenSSH only] On Cygwin, a client making
a recursive file transfer could be maniuplated by a hostile server to
perform a path-traversal attack. creating or modifying files outside
of the intended target directory. Reported by Jann Horn of Google
Project Zero.
New Features
------------
* ssh(1), sshd(8): Support "=-" syntax to easily remove methods from
algorithm lists, e.g. Ciphers=-*cbc. bz#2671
Bugfixes
--------
* sshd(1): Fix NULL dereference crash when key exchange start
messages are sent out of sequence.
* ssh(1), sshd(8): Allow form-feed characters to appear in
configuration files.
* sshd(8): Fix regression in OpenSSH 7.4 support for the
server-sig-algs extension, where SHA2 RSA signature methods were
not being correctly advertised. bz#2680
* ssh(1), ssh-keygen(1): Fix a number of case-sensitivity bugs in
known_hosts processing. bz#2591 bz#2685
* ssh(1): Allow ssh to use certificates accompanied by a private key
file but no corresponding plain *.pub public key. bz#2617
* ssh(1): When updating hostkeys using the UpdateHostKeys option,
accept RSA keys if HostkeyAlgorithms contains any RSA keytype.
Previously, ssh could ignore RSA keys when only the ssh-rsa-sha2-*
methods were enabled in HostkeyAlgorithms and not the old ssh-rsa
method. bz#2650
* ssh(1): Detect and report excessively long configuration file
lines. bz#2651
* Merge a number of fixes found by Coverity and reported via Redhat
and FreeBSD. Includes fixes for some memory and file descriptor
leaks in error paths. bz#2687
* ssh-keyscan(1): Correctly hash hosts with a port number. bz#2692
* ssh(1), sshd(8): When logging long messages to stderr, don't truncate
"\r\n" if the length of the message exceeds the buffer. bz#2688
* ssh(1): Fully quote [host]:port in generated ProxyJump/-J command-
line; avoid confusion over IPv6 addresses and shells that treat
square bracket characters specially.
* ssh-keygen(1): Fix corruption of known_hosts when running
"ssh-keygen -H" on a known_hosts containing already-hashed entries.
* Fix various fallout and sharp edges caused by removing SSH protocol
1 support from the server, including the server banner string being
incorrectly terminated with only \n (instead of \r\n), confusing
error messages from ssh-keyscan bz#2583 and a segfault in sshd
if protocol v.1 was enabled for the client and sshd_config
contained references to legacy keys bz#2686.
* ssh(1), sshd(8): Free fd_set on connection timeout. bz#2683
* sshd(8): Fix Unix domain socket forwarding for root (regression in
OpenSSH 7.4).
* sftp(1): Fix division by zero crash in "df" output when server
returns zero total filesystem blocks/inodes.
* ssh(1), ssh-add(1), ssh-keygen(1), sshd(8): Translate OpenSSL errors
encountered during key loading to more meaningful error codes.
bz#2522 bz#2523
* ssh-keygen(1): Sanitise escape sequences in key comments sent to
printf but preserve valid UTF-8 when the locale supports it;
bz#2520
* ssh(1), sshd(8): Return reason for port forwarding failures where
feasible rather than always "administratively prohibited". bz#2674
* sshd(8): Fix deadlock when AuthorizedKeysCommand or
AuthorizedPrincipalsCommand produces a lot of output and a key is
matched early. bz#2655
* Regression tests: several reliability fixes. bz#2654 bz#2658 bz#2659
* ssh(1): Fix typo in ~C error message for bad port forward
cancellation. bz#2672
* ssh(1): Show a useful error message when included config files
can't be opened; bz#2653
* sshd(8): Make sshd set GSSAPIStrictAcceptorCheck=yes as the manual page
(previously incorrectly) advertised. bz#2637
* sshd_config(5): Repair accidentally-deleted mention of %k token
in AuthorizedKeysCommand; bz#2656
* sshd(8): Remove vestiges of previously removed LOGIN_PROGRAM; bz#2665
* ssh-agent(1): Relax PKCS#11 whitelist to include libexec and
common 32-bit compatibility library directories.
* sftp-client(1): Fix non-exploitable integer overflow in SSH2_FXP_NAME
response handling.
* ssh-agent(1): Fix regression in 7.4 of deleting PKCS#11-hosted
keys. It was not possible to delete them except by specifying
their full physical path. bz#2682
Portability
-----------
* sshd(8): Avoid sandbox errors for Linux S390 systems using an ICA
crypto coprocessor.
* sshd(8): Fix non-exploitable weakness in seccomp-bpf sandbox arg
inspection.
* ssh(1): Fix X11 forwarding on OSX where X11 was being started by
launchd. bz#2341
* ssh-keygen(1), ssh(1), sftp(1): Fix output truncation for various that
contain non-printable characters where the codeset in use is ASCII.
* build: Fix builds that attempt to link a kerberised libldns. bz#2603
* build: Fix compilation problems caused by unconditionally defining
_XOPEN_SOURCE in wide character detection.
* sshd(8): Fix sandbox violations for clock_gettime VSDO syscall
fallback on some Linux/X32 kernels. bz#2142
BACKWARDS INCOMPATIBLE: Elliptic Curve signature verification no longer returns True on success. This brings it in line with the interface's documentation, and our intent. The correct way to use :meth:`~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePublicKey.verify` has always been to check whether or not :class:`~cryptography.exceptions.InvalidSignature` was raised.
BACKWARDS INCOMPATIBLE: Dropped support for macOS 10.7 and 10.8.
BACKWARDS INCOMPATIBLE: The minimum supported PyPy version is now 5.3.
Python 3.3 support has been deprecated, and will be removed in the next cryptography release.
Add support for providing tag during :class:`~cryptography.hazmat.primitives.ciphers.modes.GCM` finalization via :meth:`~cryptography.hazmat.primitives.ciphers.AEADDecryptionContext.finalize_with_tag`.
Fixed an issue preventing cryptography from compiling against LibreSSL 2.5.x.
Added :meth:`~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePublicKey.key_size` and :meth:`~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePrivateKey.key_size` as convenience methods for determining the bit size of a secret scalar for the curve.
Accessing an unrecognized extension marked critical on an X.509 object will no longer raise an UnsupportedExtension exception, instead an :class:`~cryptography.x509.UnrecognizedExtension` object will be returned. This behavior was based on a poor reading of the RFC, unknown critical extensions only need to be rejected on certificate verification.
The CommonCrypto backend has been removed.
MultiBackend has been removed.
Whirlpool and RIPEMD160 have been deprecated.
S/MIME messages encrypted with gpgsm are sometimes not decodable by
other implementations. Discussion on gnupg-devel indicates that gpg
(via libksba) is incorrectly dropping leading zeros from the encrypted
session key. This commit adds a patch by Daiki Ueno from the
mailinglist that appears to improve interoperability. Upstream has
not yet applied it, but also has not said that it is wrong.
Fixes CVE-2017-1000367, local privilege escalation on linux.
What's new in Sudo 1.8.20p1
* Fixed "make check" when using OpenSSL or GNU crypt.
Bug #787.
* Fixed CVE-2017-1000367, a bug parsing /proc/pid/stat on Linux
when the process name contains spaces. Since the user has control
over the command name, this could potentially be used by a user
with sudo access to overwrite an arbitrary file on systems with
SELinux enabled. Also stop performing a breadth-first traversal
of /dev when looking for the device; only a hard-coded list of
directories are checked,
What's new in Sudo 1.8.20
* Added support for SASL_MECH in ldap.conf. Bug #764
* Added support for digest matching when the command is a glob-style
pattern or a directory. Previously, only explicit path matches
supported digest checks.
* New "fdexec" Defaults option to control whether a command
is executed by path or by open file descriptor.
* The embedded copy of zlib has been upgraded to version 1.2.11.
* Fixed a bug that prevented sudoers include files with a relative
path starting with the letter 'i' from being opened. Bug #776.
* Added support for command timeouts in sudoers. The command will
be terminated if the timeout expires.
* The SELinux role and type are now displayed in the "sudo -l"
output for the LDAP and SSSD backends, just as they are in the
sudoers backend.
* A new command line option, -T, can be used to specify a command
timeout as long as the user-specified timeout is not longer than
the timeout specified in sudoers. This option may only be
used when the "user_command_timeouts" flag is enabled in sudoers.
* Added NOTBEFORE and NOTAFTER command options to the sudoers
backend similar to what is already available in the LDAP backend.
* Sudo can now optionally use the SHA2 functions in OpenSSL or GNU
crypt instead of the SHA2 implementation bundled with sudo.
* Fixed a compilation error on systems without the stdbool.h header
file. Bug #778.
* Fixed a compilation error in the standalone Kerberos V authentication
module. Bug #777.
* Added the iolog_flush flag to sudoers which causes I/O log data
to be written immediately to disk instead of being buffered.
* I/O log files are now created with group ID 0 by default unless
the "iolog_user" or "iolog_group" options are set in sudoers.
* It is now possible to store I/O log files on an NFS-mounted
file system where uid 0 is remapped to an unprivileged user.
The "iolog_user" option must be set to a non-root user and the
top-level I/O log directory must exist and be owned by that user.
* Added the restricted_env_file setting to sudoers which is similar
to env_file but its contents are subject to the same restrictions
as variables in the invoking user's environment.
* Fixed a use after free bug in the SSSD backend when the fqdn
sudoOption is enabled and no hostname value is present in
/etc/sssd/sssd.conf.
* Fixed a typo that resulted in a compilation error on systems
where the killpg() function is not found by configure.
* Fixed a compilation error with the included version of zlib
when sudo was built outside the source tree.
* Fixed the exit value of sudo when the command is terminated by
a signal other than SIGINT. This was broken in sudo 1.8.15 by
the fix for Bug #722. Bug #784.
* Fixed a regression introduced in sudo 1.8.18 where the "lecture"
option could not be used in a positive boolean context, only
a negative one.
* Fixed an issue where sudo would consume stdin if it was not
connected to a tty even if log_input is not enabled in sudoers.
Bug #786.
* Clarify in the sudoers manual that the #includedir directive
diverts control to the files in the specified directory and,
when parsing of those files is complete, returns control to the
original file. Bug #775.
What's new in Sudo 1.8.19p2
* Fixed a crash in visudo introduced in sudo 1.8.9 when an IP address
or network is used in a host-based Defaults entry. Bug #766
* Added a missing check for the ignore_iolog_errors flag when
the sudoers plugin generates the I/O log file path name.
* Fixed a typo in sudo's vsyslog() replacement that resulted in
garbage being logged to syslog.
What's new in Sudo 1.8.19p1
* Fixed a bug introduced in sudo 1.8.19 that resulted in the wrong
syslog priority and facility being used.
What's new in Sudo 1.8.19
* New "syslog_maxlen" Defaults option to control the maximum size of
syslog messages generated by sudo.
* Sudo has been run against PVS-Studio and any issues that were
not false positives have been addressed.
* I/O log files are now created with the same group ID as the
parent directory and not the invoking user's group ID.
* I/O log permissions and ownership are now configurable via the
"iolog_mode", "iolog_user" and "iolog_group" sudoers Defaults
variables.
* Fixed configuration of the sudoers I/O log plugin debug subsystem.
Previously, I/O log information was not being written to the
sudoers debug log.
* Fixed a bug in visudo that broke editing of files in an include
dir that have a syntax error. Normally, visudo does not edit
those files, but if a syntax error is detected in one, the user
should get a chance to fix it.
* Warnings about unknown or unparsable sudoers Defaults entries now
include the file and line number of the problem.
* Visudo will now use the file and line number information about an
unknown or unparsable Defaults entry to go directly to the file
with the problem.
* Fixed a bug in the sudoers LDAP back-end where a negated sudoHost
entry would prevent other sudoHost entries following it from matching.
* Warnings from visudo about a cycle in an Alias entry now include the
file and line number of the problem.
* In strict mode, visudo will now use the file and line number
information about a cycle in an Alias entry to go directly to the
file with the problem.
* The sudo_noexec.so file is now linked with -ldl on systems that
require it for the wordexp() wrapper.
* Fixed linking of sudo_noexec.so on macOS systems where it must be
a dynamic library and not a module.
* Sudo's "make check" now includes a test for sudo_noexec.so
working.
* The sudo front-end now passes the user's umask to the plugin.
Previously the plugin had to determine this itself.
* Sudoreplay can now display the stdin and ttyin streams when they
are explicitly added to the filter list.
* Fixed a bug introduced in sudo 1.8.17 where the "all" setting
for verifypw and listpw was not being honored. Bug #762.
* The syslog priority (syslog_goodpri and syslog_badpri) can now
be negated or set to "none" to disable logging of successful or
unsuccessful sudo attempts via syslog.
What's new in Sudo 1.8.18p1
* When sudo_noexec.so is used, the WRDE_NOCMD flag is now added
if the wordexp() function is called. This prevents commands
from being run via wordexp() without disabling it entirely.
* On Linux systems, sudo_noexec.so now uses a seccomp filter to
disable execute access if the kernel supports seccomp. This is
more robust than the traditional method of using stub functions
that return an error.
What's new in Sudo 1.8.18
* The sudoers locale is now set before parsing the sudoers file.
If sudoers_locale is set in sudoers, it is applied before
evaluating other Defaults entries. Previously, sudoers_locale
was used when evaluating sudoers but not during the inital parse.
Bug #748.
* A missing or otherwise invalid #includedir is now ignored instead
of causing a parse error.
* During "make install", backup files are only used on HP-UX where
it is not possible to unlink a shared object that is in use.
This works around a bug in ldconfig on Linux which could create
links to the backup shared library file instead of the current
one.
* Fixed a bug introduced in 1.8.17 where sudoers entries with long
commands lines could be truncated, preventing a match. Bug #752.
* The fqdn, runas_default and sudoers_locale Defaults settings are
now applied before any other Defaults settings since they can
change how other Defaults settings are parsed.
* On systems without the O_NOFOLLOW open(2) flag, when the NOFOLLOW
flag is set, sudoedit now checks whether the file is a symbolic link
before opening it as well as after the open. Bug #753.
* Sudo will now only resolve a user's group IDs to group names
when sudoers includes group-based permissions. Group lookups
can be expensive on some systems where the group database is
not local.
* If the file system holding the sudo log file is full, allow
the command to run unless the new ignore_logfile_errors Defaults
option is disabled. Bug #751.
* The ignore_audit_errors and ignore_iolog_errors Defaults options
have been added to control sudo's behavior when it is unable to
write to the audit and I/O logs.
* Fixed a bug introduced in 1.8.17 where the SIGPIPE signal handler
was not being restored when sudo directly executes the command.
* Fixed a bug where "sudo -l command" would indicate that a command
was runnable even when denied by sudoers when using the LDAP or
SSSD backends.
* The match_group_by_gid Defaults option has been added to allow
sites where group name resolution is slow and where sudoers only
contains a small number of groups to match groups by group ID
instead of by group name.
* Fixed a bug on Linux where a 32-bit sudo binary could fail with
an "unable to allocate memory" error when run on a 64-bit system.
Bug #755
* When parsing ldap.conf, sudo will now only treat a '#' character
as the start of a comment when it is at the beginning of the
line.
* Fixed a potential crash when auditing is enabled and the audit
function fails with an error. Bug #756
* Norwegian Nynorsk translation for sudo from translationproject.org.
* Fixed a typo that broke short host name matching when the fqdn
flag is enabled in sudoers. Bug #757
* Negated sudoHost attributes are now supported by the LDAP and
SSSD backends.
* Fixed matching entries in the LDAP and SSSD backends when a
RunAsGroup is specified but no RunAsUser is present.
* Fixed "sudo -l" output in the LDAP and SSSD backends when a
RunAsGroup is specified but no RunAsUser is present.
0.14.2
- Certbot 0.14.0 included a bug where Certbot would create a temporary
log file (usually in /tmp) if the program exited during argument parsing.
0.14.1
- Certbot now works with configargparse 0.12.0.
- Issues with the Apache plugin and Augeas 1.7+ have been resolved.
- A problem where the Nginx plugin would fail to install certificates on
systems that had the plugin's SSL/TLS options file from 7+ months ago
has been fixed.
1.8.2 - 2017-05-26
~~~~~~~~~~~~~~~~~~
* Fixed a compilation bug affecting OpenSSL 1.1.0f.
* Updated Windows and macOS wheels to be compiled against OpenSSL 1.1.0f.
17.0.0 (2017-05-23)
-------------------
Deprecations:
^^^^^^^^^^^^^
- Since Chrome 58 and Firefox 48 both don't accept certificates that contain only a Common Name, its usage is hereby deprecated in ``service_identity`` too.
We have been raising a warning since 16.0.0 and the support will be removed in mid-2018 for good.
Changes:
^^^^^^^^
- When ``service_identity.SubjectAltNameWarning`` is raised, the Common Name of the certificate is now included in the warning message.
`#17 <https://github.com/pyca/service_identity/pull/17>`_
- Added ``cryptography.x509`` backend for verifying certificates.
`#18 <https://github.com/pyca/service_identity/pull/18>`_
- Wildcards (``*``) are now only allowed if they are the leftmost label in a certificate.
This is common practice by all major browsers.
`#19 <https://github.com/pyca/service_identity/pull/19>`_

RCD_SCRIPT_WRK.<script> was set previously to prevent a name conflict
with ${WRKSRC} because in the past, it defaulted to ${WRKDIR}/<script>.
This has since been changed to default to ${WRKDIR}/.rc.d/<script> to
prevent unintended name collisions, which makes this definition no longer
needed.

Upstream changes:
1.18.2 2017-02-20
[Bug] #895: Fix a bug in server-mode concerning multiple interactive
auth steps (which were incorrectly responded to). Thanks to Dennis
Kaarsemaker for catch & patch.
[Bug] #713: (via #714 and #889) Don't pass initialization vectors
to PyCrypto when dealing with counter-mode ciphers; newer PyCrypto
versions throw an exception otherwise (older ones simply ignored
this parameter altogether). Thanks to @jmh045000 for report &
patches.
[Bug] #44: (via #891) SSHClient now gives its internal Transport
a handle on itself, preventing garbage collection of the client
until the session is closed. Without this, some code which returns
stream or transport objects without the client that generated
them, would result in premature session closure when the client
was GCd. Credit: @w31rd0 for original report, Omer Anson for the
patch.
[Bug] #862: (via #863) Avoid test suite exceptions on platforms
lacking errno.ETIME (which seems to be some FreeBSD and some
Windows environments.) Thanks to Sofian Brabez.
[Bug] #853: Tweak how RSAKey.__str__ behaves so it doesn't
cause TypeError under Python 3. Thanks to Francisco Couzo for
the report.
[Support] #866: (also #838) Remove an old test-related file we
don't support, and add PyPy to Travis-CI config. Thanks to
Pierce Lopez for the final patch and Pedro Rodrigues for an
earlier edition.
1.18.1 2016-12-12
[Bug] #859: (via #860) A tweak to the original patch implementing
#398 was not fully applied, causing calls to invoke_shell to
fail with AttributeError. This has been fixed. Patch credit:
Kirk Byers.
1.18.0 2016-12-09
[Feature] #398: Add an environment dict argument to
Client.exec_command (plus the lower level Channel.update_environment
and Channel.set_environment_variable methods) which implements
the env SSH message type. This means the remote shell environment
can be set without the use of VARNAME=value shell tricks,
provided the server's AcceptEnv lists the variables you need
to set. Thanks to Philip Lorenz for the pull request.
[Feature] #780: (also #779, and may help users affected by
#520) Add an optional timeout parameter to Transport.start_client
(and feed it the value of the configured connection timeout
when used within SSHClient.) This helps prevent situations
where network connectivity isn't timing out, but the remote
server is otherwise unable to service the connection in a timely
manner. Credit to @sanseihappa.
[Support] #819: Document how lacking gmp headers at install
time can cause a significant performance hit if you build
PyCrypto from source. (Most system-distributed packages already
have this enabled.)
[Support] #854: Fix incorrect docstring/param-list for
Transport.auth_gssapi_keyex so it matches the real signature.
Caught by @Score_Under.
[Support] #792: Minor updates to the README and demos; thanks to Alan Yee.
[Support] #801: Skip a Unix-only test when on Windows; thanks to Gabi Davar.
For pre-1.18.0 changes, see
http://www.paramiko.org/changelog.html
The 5.6.5 release was mostly a maintenance release. The release included two CVE fixes.
The first, CVE-2016-7420, was a procedural finding due to external build systems failing to define NDEBUG for release builds. The gap was the project's failure to tell users to define NDEBUG. The second, CVE-2016-7544, was a potential memory corruption on Windows platforms when using Microsoft compilers due to use of _malloca and _freea.
Due to CVE-2016-7420 and the possibility for an unwanted assert to egress data, users and distros are encouraged to recompile the library and all dependent programs.
Pkgsrc changes:
Adapt PLIST.
Upstream changes:
* Version 3.5.12 (released 2017-05-11)
** libgnutls: enabled TCP Fast open for MacOSX. Patch by Tim Ruehsen.
** libgnutls: gnutls_x509_crt_check_hostname2() no longer matches IP addresses
against DNS fields of certificate (CN or DNSname). The previous behavior
was to tolerate some misconfigured servers, but that was non-standard
and skipped any IP constraints present in higher level certificates.
** libgnutls: when converting to IDNA2008, fallback to IDNA2003
(i.e., transitional encoding) if the domain cannot be converted.
That provides maximum compatibility with browsers like firefox
that perform the same conversion.
** libgnutls: fix issue in RSA-PSK client callback which resulted
in no username being sent to the peer. Patch by Nicolas Dufresne.
** libgnutls: fix regression causing stapled extensions in trust modules not
to be considered.
** certtool: introduced the email_protection_key option. This
option was introduced in documentation for certtool without an
implementation of it. It is a shortcut for option 'key_purpose_oid
= 1.3.6.1.5.5.7.3.4'.
** certtool: made printing of key ID and key PIN consistent between
certificates, public keys, and private keys. That is the private
key printing now uses the same format as the rest.
** gnutls-cli: introduced the --sni-hostname option. This allows overriding the
hostname advertised to the peer.
** API and ABI modifications:
No changes since last version.
* Version 3.5.11 (released 2017-04-07)
** gnutls.pc: do not include libtool options into Libs.private.
** libgnutls: Fixed issue when rehandshaking without a client certificate in
a session which initially used one. Reported by Frantisek Sumsal.
** libgnutls: Addressed read of 4 bytes past the end of buffer in OpenPGP
certificate parsing. Issues found using oss-fuzz project and were fixed
by Alex Gaynor:
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=737https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=824
** libgnutls: Introduced locks in gnutls_pkcs11_privkey_t structure access.
That allows PKCS#11 operations such as signing to be performed with the
same object from multiple threads.
** libgnutls: Added support for MacOSX key chain for obtaining
trust store's root CA certificates. That is,
gnutls_x509_trust_list_add_system_trust() and
gnutls_certificate_set_x509_system_trust() will load the certificates
from the key chain. That also means that we no longer check for a
default trust store file in configure when building on MacOSX (unless
explicitly asked to). Patch by David Caldwell.
** libgnutls: when disabling OpenPGP authentication, the resulting library
is ABI compatible (with openpgp related functions being stubs that fail
on invocation).
** API and ABI modifications:
No changes since last version.
* Version 3.5.10 (released 2017-03-06)
** gnutls.pc: do not include libidn2 in Requires.private. The
libidn2 versions available do not include libidn2.pc, thus the
inclusion was causing pkg-config issues. Instead we include
-lidn2 in Libs.private when compile against libidn2.
** libgnutls: optimized access to subject alternative names (SANs)
in parsed certificates. The previous implementation assumed a
small number of SANs in a certificate, with repeated calls to
ASN.1 decoding of the extension without any intermediate caching.
That caused delays in certificates with a long list of names in
functions such as gnutls_x509_crt_check_hostname(). With the
current code, the SANs are parsed once on certificate import.
Resolves gitlab issue #165.
** libgnutls: Addressed integer overflow resulting to invalid memory
write in OpenPGP certificate parsing. Issue found using oss-fuzz
project: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=420
[GNUTLS-SA-2017-3A]
** libgnutls: Addressed read of 1 byte past the end of buffer in OpenPGP
certificate parsing. Issue found using oss-fuzz project:
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=391
** libgnutls: Addressed crashes in OpenPGP certificate parsing, related
to private key parser. No longer allow OpenPGP certificates (public keys)
to contain private key sub-packets. Issue found using oss-fuzz project:
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=354https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=360 [GNUTLS-SA-2017-3B]
** libgnutls: Addressed large allocation in OpenPGP certificate parsing, that
could lead in out-of-memory condition. Issue found using oss-fuzz project,
and was fixed by Alex Gaynor:
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=392 [GNUTLS-SA-2017-3C]
** libgnutls: Print the key PIN value used by the HPKP protocol as per RFC7469
when printing certificate information.
** libgnutls: gnutls_ocsp_resp_verify_direct() and gnutls_ocsp_resp_verify()
flags can be set from the gnutls_certificate_verify_flags enumeration.
This allows the functions to pass the same flags available for certificates
to the verification function (e.g., GNUTLS_VERIFY_DISABLE_TIME_CHECKS or
GNUTLS_VERIFY_ALLOW_BROKEN).
** libgnutls: gnutls_store_commitment() can accept flag
GNUTLS_SCOMMIT_FLAG_ALLOW_BROKEN. This is to allow the function to operate
in applications which use SHA1 for example, after SHA1 is deprecated.
** certtool: No longer ignore the 'add_critical_extension' template option if
the 'add_extension' option is not present.
** gnutls-cli: Added LMTP, POP3, NNTP, Sieve and PostgreSQL support to the
starttls-proto command. Patch by Robert Scheck.
** API and ABI modifications:
No changes since last version.
2016.74 - 21 July 2016
- Security: Message printout was vulnerable to format string injection.
If specific usernames including "%" symbols can be created on a system
(validated by getpwnam()) then an attacker could run arbitrary code as root
when connecting to Dropbear server.
A dbclient user who can control username or host arguments could potentially
run arbitrary code as the dbclient user. This could be a problem if scripts
or webpages pass untrusted input to the dbclient program.
CVE-2016-7406
https://secure.ucc.asn.au/hg/dropbear/rev/b66a483f3dcb
- Security: dropbearconvert import of OpenSSH keys could run arbitrary code as
the local dropbearconvert user when parsing malicious key files
CVE-2016-7407
https://secure.ucc.asn.au/hg/dropbear/rev/34e6127ef02e
- Security: dbclient could run arbitrary code as the local dbclient user if
particular -m or -c arguments are provided. This could be an issue where
dbclient is used in scripts.

(IPv4, IPv6, round robin DNS)
- Fix all compile warnings, many patches from Gaël Portay
Note that configure with -Werror may not be successful on some platforms (OS X)
and some configuration options may still result in unused variable
warnings.
- Use TCP Fast Open on Linux if available. Saves a round trip at connection
to hosts that have previously been connected.
Needs a recent Linux kernel and possibly "sysctl -w net.ipv4.tcp_fastopen=3"
Client side is disabled by default pending further compatibility testing
with networks and systems.
- Increase maximum command length to 9000 bytes
- Free memory before exiting, patch from Thorsten Horstmann. Useful for
Dropbear ports to embedded systems and for checking memory leaks
with valgrind. Only partially implemented for dbclient.
This is disabled by default, enable with DROPBEAR_CLEANUP in sysoptions.h
- DROPBEAR_DEFAULT_CLI_AUTHKEY setting now always prepends home directory unless
there is a leading slash (~ isn't treated specially)

for ECC key exchange. sha1 is the first preference still for performance.
- Fix installing dropbear.8 in a separate build directory, from Like Ma
- Allow configure to succeed if libtomcrypt/libtommath are missing, from Elan Ruusamäe
- Don't crash if ssh-agent provides an unknown type of key. From Catalin Patulea
- Minor bug fixes, a few issues found by Coverity scan
2014.66 - Thursday 23 October 2014
- Use the same keepalive handling behaviour as OpenSSH. This will work better
with some SSH implementations that have different behaviour with unknown
message types.
- Don't reply with SSH_MSG_UNIMPLEMENTED when we receive a reply to our own
keepalive message
- Set $SSH_CLIENT to keep bash happy, patch from Ryan Cleere

- Don't exit the client if the local user entry can't be found, thanks to iquaba
2014.64 - Sunday 27 July 2014
- Fix compiling with ECDSA and DSS disabled
- Don't exit abruptly if too many outgoing packets are queued for writev(). Patch
thanks to Ronny Meeus
- The -K keepalive option now behaves more like OpenSSH's "ServerAliveInterval".
If no response is received after 3 keepalives then the session is terminated. This
will close connections faster than waiting for a TCP timeout.
- Rework TCP priority setting. New settings are
if (connecting || ptys || x11) tos = LOWDELAY
else if (tcp_forwards) tos = 0
else tos = BULK
Thanks to Catalin Patulea for the suggestion.
- Improve handling of many concurrent new TCP forwarded connections, should now
be able to handle as many as MAX_CHANNELS. Thanks to Eduardo Silva for reporting
and investigating it.
- Make sure that exit messages from the client are printed, regression in 2013.57
- Use monotonic clock where available, timeouts won't be affected by system time
changes
- Add -V for version
2014.63 - Wednesday 19 February 2014
- Fix ~. to terminate a client interactive session after waking a laptop
from sleep.
- Changed port separator syntax again, now using host^port. This is because
IPv6 link-local addresses use %. Reported by Gui Iribarren
- Avoid constantly relinking dropbearmulti target, fix "make install"
for multi target, thanks to Mike Frysinger
- Avoid getting stuck in a loop writing huge key files, reported by Bruno
Thomsen
- Don't link dropbearkey or dropbearconvert to libz or libutil,
thanks to Nicolas Boos
- Fix linking -lcrypt on systems without /usr/lib, thanks to Nicolas Boos
- Avoid crash on exit due to cleaned up keys before last packets are sent,
debugged by Ronald Wahl
- Fix a race condition in rekeying where Dropbear would exit if it received a
still-in-flight packet after initiating rekeying. Reported by Oliver Metz.
This is a longstanding bug but is triggered more easily since 2013.57
- Fix README for ecdsa keys, from Catalin Patulea
- Ensure that generated RSA keys are always exactly the length
requested. Previously Dropbear always generated N+16 or N+15 bit keys.
Thanks to Unit 193
- Fix DROPBEAR_CLI_IMMEDIATE_AUTH mode which saves a network round trip if the
first public key succeeds. Still not enabled by default, needs more
compatibility testing with other implementations.
- Fix for port 0 forwarding in the client and port forwarding with Apache MINA SSHD.
- Fix for bad system linux/pkt-sched.h header file with older Linux
kernels, from Steve Dover
- Fix signal handlers so that errno is saved, thanks to Erik Ahlén for a patch
and Mark Wickham for independently spotting the same problem.
Noteworthy changes in version 2.1.21 (2017-05-15)

bug was introduced with version 2.1.20. Note that the default
pubring.kbx format was not affected.
* gpg,dirmngr: Removed the skeleton config file support. The
system's standard methods for providing default configuration
files should be used instead.
