Scientific Linux Security Update : gdm on SL6.x i386/x86_64

medium Nessus Plugin ID 60998

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

The GNOME Display Manager (GDM) provides the graphical login screen, shown shortly after boot up, log out, and when user-switching.

A race condition flaw was found in the way GDM handled the cache directories used to store users' dmrc and face icon files. A local attacker could use this flaw to trick GDM into changing the ownership of an arbitrary file via a symbolic link attack, allowing them to escalate their privileges. (CVE-2011-0727)

We would like to thank Sebastian Krahmer of the SuSE Security Team for reporting this issue.

Solution

Update the affected packages.
