gdm security update

CentOS Errata and Security Advisory CESA-2007:0777

Gdm (the GNOME Display Manager) is a highly configurable reimplementation
of xdm, the X Display Manager. Gdm allows you to log into your system with
the X Window System running and supports running several different X
sessions on your local machine at the same time.

A flaw was found in the way Gdm listens on its unix domain socket. A local
user could crash a running X session by writing malicious data to Gdm’s
unix domain socket. (CVE-2007-3381)

All users of gdm should upgrade to this updated package, which contains a
backported patch that resolves this issue.

Red Hat would like to thank JLANTHEA for reporting this issue.
