Update sudo to 1.9.3
Sudo version 1.9.3 is now available. In addition to bug fixes,
Sudo 1.9.3 adds support for per-command chroot and working directory
settings and command line options. Sudo 1.9.3 also features more
detailed messages when there is a syntax error in the sudoers file,
as well as better recovery from syntax errors.

Major changes between sudo 1.9.2 and 1.9.3
* sudoedit will now prompt the user before overwriting an existing
file with one that is zero-length after editing. Bug #922.
* Fixed building the Python plugin on systems with a compiler that
doesn't support symbol hiding.
* Sudo now uses a linker script to hide symbols even when the
compiler has native symbol hiding support. This should make it
easier to detect omissions in the symbol exports file, regardless
of the platform.
* Fixed the libssl dependency in Debian packages for older releases
that use libssl1.0.0.
* Sudo and visudo now provide more detailed messages when a syntax
error is detected in sudoers. The offending line and token are
now displayed. If the parser was generated by GNU bison,
additional information about what token was expected is also
displayed. Bug #841.
* Sudoers rules must now end in either a newline or the end-of-file.
Previously, it was possible to have multiple rules on a single
line, separated by white space. The use of an end-of-line
terminator makes it possible to display accurate error messages.
* Sudo no longer refuses to run if a syntax error in the sudoers
file is encountered. The entry with the syntax error will be
discarded and sudo will continue to parse the file. This makes
recovery from a syntax error less painful on systems where sudo
is the primary method of superuser access. The historic behavior
can be restored by add "error_recovery=false" to the sudoers
plugin's optional arguments in sudo.conf. Bug #618.
* Fixed the sample_approval plugin's symbol exports file for systems
where the compiler doesn't support symbol hiding.
* Fixed a regression introduced in sudo 1.9.1 where arguments to
the "sudoers_policy" plugin in sudo.conf were not being applied.
The sudoers file is now parsed by the "sudoers_audit" plugin,
which is loaded implicitly when "sudoers_policy" is listed in
sudo.conf. Starting with sudo 1.9.3, if there are plugin arguments
for "sudoers_policy" but "sudoers_audit" is not listed, those
arguments will be applied to "sudoers_audit" instead.
* The user's resource limits are now passed to sudo plugins in
the user_info list. A plugin cannot determine the limits
itself because sudo changes the limits while it runs to prevent
* It is now possible to set the working directory or change the
root directory on a per-command basis using the CWD and CHROOT
options. There are also new Defaults settings, runchroot and
runcwd, that can be used to set the working directory or root
directory on a more global basis.
* New -D (--chdir) and -R (--chroot) command line options can be
used to set the working directory or root directory if the sudoers
file allows it. This functionality is not enabled by default
and must be explicitly enabled in the sudoers file.
