An attacker could use this issue to cause X.Org to crash, or to possibly execute arbitrary code. (CVE-2013-4396) It was discovered that non-root X.Org X servers such as Xephyr incorrectly used cached xkb files. A local attacker could use this flaw to cause a xkb cache file to be loaded by another user, resulting in a denial of service. (CVE-2013-1056).
