DESCRIPTION:
A vulnerability has been reported in Sudo, which can be exploited by
malicious, local users to perform certain actions with escalated
privileges.

The vulnerability is caused due to a logic error in the processing of
Runas groups when the "-u" option is specified. This can be exploited
to execute commands that are configured in a sudoers file as an
arbitrary user if an allowed Runas group is also configured in the
entry.

The vulnerability is reported in version 1.7.0 through 1.7.4p3.

SOLUTION:
Update to version 1.7.4p4.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Markus Wuethrich, Swiss Post - PostFinance.
