RHSA-2010:0657: Low: gdm security and bug fix update

First published: Thu Aug 26 2010(Updated: )

The GNOME Display Manager (GDM) is a configurable re-implementation of XDM,<br>the X Display Manager. GDM allows you to log in to your system with the X<br>Window System running, and supports running several different X sessions on<br>your local machine at the same time.<br>A flaw was found in the way the gdm package was built. The gdm package was<br>missing TCP wrappers support on 64-bit platforms, which could result in an<br>administrator believing they had access restrictions enabled when they did<br>not. (CVE-2007-5079)<br>This update also fixes the following bug:<br><li> sometimes the system would hang instead of properly shutting down when</li> a user chose "Shut down" from the login screen. (BZ#625818)<br>All users should upgrade to this updated package, which contains backported<br>patches to correct these issues. GDM must be restarted for this update to<br>take effect. Rebooting achieves this, but changing the runlevel from 5 to 3<br>and back to 5 also restarts GDM.<br>
