Category:	CentOS Local Security Checks
Title:	CentOS Update for gdm CESA-2013:1213 centos5
Summary:	The remote host is missing an update for the 'gdm'; package(s) announced via the referenced advisory.
Description:	Summary: The remote host is missing an update for the 'gdm' package(s) announced via the referenced advisory. Vulnerability Insight: The GNOME Display Manager (GDM) provides the graphical login screen, shown shortly after boot up, log out, and when user-switching. A race condition was found in the way GDM handled the X server sockets directory located in the system temporary directory. An unprivileged user could use this flaw to perform a symbolic link attack, giving them write access to any file, allowing them to escalate their privileges to root. (CVE-2013-4169) Note that this erratum includes an updated initscripts package. To fix CVE-2013-4169, the vulnerable code was removed from GDM and the initscripts package was modified to create the affected directory safely during the system boot process. Therefore, this update will appear on all systems, however systems without GDM installed are not affected by this flaw. Red Hat would like to thank the researcher with the nickname vladz for reporting this issue. All users should upgrade to these updated packages, which correct this issue. The system must be rebooted for this update to take effect. Affected Software/OS: gdm on CentOS 5 Solution: Please install the updated packages. CVSS Score: 6.9 CVSS Vector: AV:L/AC:M/Au:N/C:C/I:C/A:C
