Debian DSA-2319-1 : policykit-1 - race condition

medium Nessus Plugin ID 56414

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Neel Mehta discovered that a race condition in Policykit, a framework for managing administrative policies and privileges, allowed local users to elevate privileges by executing a setuid program from pkexec.

The oldstable distribution (lenny) does not contain the policykit-1 package.

Solution

Upgrade the policykit-1 packages.

For the stable distribution (squeeze), this problem has been fixed in version 0.96-4+squeeze1.
