Ubuntu 9.10 / 10.04 LTS / 10.10 : gdm vulnerability (USN-1099-1)

medium Nessus Plugin ID 53238

Synopsis

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

Description

Sebastian Krahmer discovered that GDM (GNOME Display Manager) did not properly drop privileges when handling the cache directories used to store users' dmrc and face icon files. This could allow a local attacker to change the ownership of arbitrary files, thereby gaining root 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 gdm package.
