Ubuntu 8.04 LTS / 10.04 LTS / 11.10 / 12.04 LTS / 12.10 : sudo vulnerability (USN-1754-1)

medium Nessus Plugin ID 64969

Language:

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Marco Schoepl discovered that Sudo incorrectly handled time stamp files when the system clock is set to epoch. A local attacker could use this issue to run Sudo commands without a password prompt.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected sudo and / or sudo-ldap packages.
