Detail
Problem Description: An updated gdm package that fixes a security issue and a bug is now available. This update has been rated as having low security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64 3. Problem description: 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. Marcus Meissner discovered a race condition issue in the way Gdm modifies the permissions on the .ICEauthority file. A local attacker could exploit this flaw to gain privileges. Due to the nature of the flaw, however, a successful exploitation was unlikely. (CVE-2006-1057) This erratum also includes a bug fix to correct the pam configuration for the audit system. All users of gdm should upgrade to this updated package, which contains backported patches to resolve these issues. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command: up2date For information on how to install packages manually, refer to the following Web page for the System Administration or Customization guide specific to your system: http://www.redhat.com/docs/manuals/enterprise/ 5.
