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.
