Major changes between version 1.9.7rc1 and 1.9.7b2:
- The configure script now outputs a summary of the user-configurable
options at the end, separate from output of configure script tests.
- Corrected the description of which groups may be specified via the
-g option in the Runas_Spec section.
- Updated translations from
Major changes between version 1.9.7b2 and 1.9.7b1:
- Fixed a bug that prevented the log_server_verify sudoers
option from taking effect.
- The sudo_sendlog utility has a new -s option
to cause it to stop sending I/O records after a user-specified elapsed
time. This can be used to test the I/O log restart functionality
- Fixed a crash introduced in sudo 1.9.4 in sudo_logsrvd when
attempting to restart an interrupted I/O log transfer.
- The TLS connection timeout in the sudoers log client was previously
hard-coded to 10 seconds. It now uses the value of
- Updated translations from
Major changes between version 1.9.7b1 and 1.9.6p1:
- The fuzz Makefile target now runs all the fuzzers for 8192
passes (can be overridden via the FUZZ_RUNS variable).
This makes it easier to run the fuzzers in-tree. To run a fuzzer
indefinitely, set FUZZ_RUNS=-1, e.g. make FUZZ_RUNS=-1 fuzz.
- Fixed fuzzing on FreeBSD where the ld.lld linker returns an
error by default when a symbol is multiply-defined.
- Added support for determining local IPv6 addresses on systems
that lack the getifaddrs() function. This now works on AIX,
HP-UX and Solaris (at least).
- Fixed a bug introduced in sudo 1.9.6 that caused sudo -V to
report a usage error. Also, when invoked as sudoedit, sudo now
allows a more restricted set of options that matches the usage
statement and documentation.
GitHub Issue #95.
- Fixed a crash in sudo_sendlog when the specified certificate
or key does not exist or is invalid.
- Fixed a compilation error when sudo is configured with the
- Sudo's limited support for SUCCESS=return entries in nsswitch.conf
is now documented.
- Sudo now requires autoconf 2.70 or higher to regenerate the
- sudo_logsrvd now has a relay mode which can be used to create
a hierarchy of log servers. By default, when a relay server is
defined, messages from the client are forwarded immediately to
the relay. However, if the store_first setting is enabled,
the log will be stored locally until the command completes and
- Sudo now links with OpenSSL by default if it is available unless
the --disable-openssl configure option is used or both the
--disable-log-client and --disable-log-server
configure options are specified.
- Fixed configure's Python version detection when the version minor
number is more than a single digit, for example Python 3.10.
- The sudo Python module tests now pass for Python 3.10.
- Sudo will now avoid changing the datasize resource limit
as long as the existing value is at least 1GB. This works around
a problem on 64-bit HP-UX where it is not possible to exactly
restore the original datasize limit.
- Fixed a race condition that could result in a hang when sudo is
executed by a process where the SIGCHLD handler is set to SIG_IGN.
This fixes the bug described by GitHub PR #98.
- Fixed an out-of-bounds read in sudoedit and visudo when the
EDITOR, VISUAL or SUDO_EDITOR environment variables end in an
unescaped backslash. Also fixed the handling of quote characters
that are escaped by a backslash.
GitHub Issue #99.
