Major changes between sudo 1.9.8 and 1.9.7p2:
* It is now possible to transparently intercepting sub-commands
executed by the original command run via sudo. Intercept support
is implemented using LD_PRELOAD (or the equivalent supported by
the system) and so has some limitations. The two main limitations
are that only dynamic executables are supported and only the
execl, execle, execlp, execv, execve, execvp, and execvpe library
functions are currently intercepted. Its main use case is to
support restricting privileged shells run via sudo.
To support this, there is a new "intercept" Defaults setting and
an INTERCEPT command tag that can be used in sudoers. For example:
Cmnd_Alias SHELLS=/bin/bash, /bin/sh, /bin/csh, /bin/ksh, /bin/zsh
Defaults!SHELLS intercept
would cause sudo to run the listed shells in intercept mode.
This can also be set on a per-rule basis. For example:
Cmnd_Alias SHELLS=/bin/bash, /bin/sh, /bin/csh, /bin/ksh, /bin/zsh
chuck ALL = INTERCEPT: SHELLS
would only apply intercept mode to user "chuck" when running one
of the listed shells.
In intercept mode, sudo will not prompt for a password before
running a sub-command and will not allow a set-user-ID or
set-group-ID program to be run by default. The new
intercept_authenticate and intercept_allow_setid sudoers settings
can be used to change this behavior.
* The new "log_subcmds" sudoers setting can be used to log additional
commands run in a privileged shell. It uses the same mechanism as
the intercept support described above and has the same limitations.
* Support for logging sudo_logsrvd errors via syslog or to a file.
Previously, most sudo_logsrvd errors were only visible in the
debug log.
* Better diagnostics when there is a TLS certificate validation error.
* Using the "+=" or "-=" operators in a Defaults setting that takes
a string, not a list, now produces a warning from sudo and a
syntax error from inside visudo.
* Fixed a bug where the "iolog_mode" setting in sudoers and sudo_logsrvd
had no effect when creating I/O log parent directories if the I/O log
file name ended with the string "XXXXXX".
* Fixed a bug in the sudoers custom prompt code where the size
parameter that was passed to the strlcpy() function was incorrect.
No overflow was possible since the correct amount of memory was
already pre-allocated.
* The mksigname and mksiglist helper programs are now built with
the host compiler, not the target compiler, when cross-compiling.
Bug #989.
* Fixed compilation error when the --enable-static-sudoers configure
option was specified. This was due to a typo introduced in sudo
1.9.7. GitHub PR #113.

pfSense-pkg-suricata-5.0.4_RELENG_2_4_5
This package update provides support for the latest 5.0.4 Suricata binary from the upstream 5.x branch and fixes four bugs. One new feature is also added.
New Features:
Bug Fixes:
Check that LRO, TSO and all Hardware Checksumming is disabled in pfSense config.xml when user enables and saves "IPS Inline" mode configuration.
Potential YAML key indentation issue with libhtp policy settings in suricata.yaml conf file.
Add input validation to prevent users from choosing Netmap Inline IPS Mode with incompatible physical NICs. See Redmine Issue #10950 from Snort for details. Suricata needs the same input validation.
Complete implementation of fix for Redmine Issue 9789 (from Snort) since Suricata is susceptible to the same issues.
