RHBA-2012:1446 - gdm bug fix update

Synopsis

gdm bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated gdm packages that fix a bug are now available for Red Hat Enterprise Linux 6.

Description

The GNOME Display Manager (GDM) 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.

This update fixes the following bug:

  • When gdm was used to connect to a server via XDMCP (X Display Manager Control Protocol), another connection to a remote system using the "ssh -X" command resulted in wrong authorization with the X server. Consequently, applications such as xterm could not be displayed on the remote system. This update provides a compatible MIT-MAGIC-COOKIE-1 key in the described scenario, thus fixing this bug. (BZ#860646)

All users of gdm are advised to upgrade to these updated packages, which fix this bug.

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258
