Debian DSA-2205-1 : gdm3 - privilege escalation

medium Nessus Plugin ID 53198

Synopsis

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

Description

Sebastian Krahmer discovered that GDM 3, the GNOME Display Manager, does not properly drop privileges when manipulating files related to the logged-in user. As a result, local users can gain root privileges.

The oldstable distribution (lenny) does not contain a gdm3 package.
The gdm package is not affected by this issue.

Solution

Upgrade the gdm3 packages.

For the stable distribution (squeeze), this problem has been fixed in version 2.30.5-6squeeze2.
