 Mandriva Linux Security Advisory                         MDVSA-2013:260
 http://www.mandriva.com/en/support/security/
 _______________________________________________________________________

 Package : x11-server
 Date    : October 28, 2013
 Affected: Enterprise Server 5.0
 _______________________________________________________________________

 Problem Description:

 Multiple vulnerabilities has been discovered and corrected in
 x11-server:
 
 The fbComposite function in fbpict.c in the Render extension in the
 X server in X.Org X11R7.1 allows remote authenticated users to cause
 a denial of service (memory corruption and daemon crash) or possibly
 execute arbitrary code via a crafted request, related to an incorrect
 macro definition (CVE-2010-1166).
 
 The LockServer function in os/utils.c in X.Org xserver before 1.11.2
 allows local users to determine the existence of arbitrary files via a
 symlink attack on a temporary lock file, which is handled differently
 if the file exists (CVE-2011-4028).
 
 The LockServer function in os/utils.c in X.Org xserver before 1.11.2
 allows local users to change the permissions of arbitrary files to
 444, read those files, and possibly cause a denial of service (removed
 execution permission) via a symlink attack on a temporary lock file
 (CVE-2011-4029).
 
 X.Org X server before 1.13.4 and 1.4.x before 1.14.1 does not
 properly restrict access to input events when adding a new hot-plug
 device, which might allow physically proximate attackers to obtain
 sensitive information, as demonstrated by reading passwords from a tty
 (CVE-2013-1940).
 
 Use-after-free vulnerability in the doImageText function in
 dix/dixfonts.c in the xorg-server module before 1.14.4 in X.Org X11
 allows remote authenticated users to cause a denial of service (daemon
 crash) or possibly execute arbitrary code via a crafted ImageText
 request that triggers memory-allocation failure (CVE-2013-4396).
 
 The updated packages have been patched to correct these issues.
