Ubuntu 10.04 LTS / 12.04 LTS / 12.10 / 13.04 : policykit-1 vulnerability (USN-1953-1)

high Nessus Plugin ID 69971

Language:

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

It was discovered that polkit didn't allow applications to use the pkcheck tool in a way which prevented a race condition in the UID lookup. A local attacker could use this flaw to possibly escalate privileges.

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 policykit-1 package.
