http://www.mandriva.com/security/
_______________________________________________________________________

Package : gdm
Date : May 9, 2006
Affected: 2006.0
_______________________________________________________________________

Problem Description:

A race condition in daemon/slave.c in gdm before 2.14.1 allows local
users to gain privileges via a symlink attack when gdm performs chown
and chgrp operations on the .ICEauthority file.

Packages have been patched to correct this issue.
