Detail
| A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 13.04 - Ubuntu 12.10 - Ubuntu 12.04 LTS Summary: The X.Org X server could be made to crash or run programs as an administrator if it received specially crafted input. Software Description: - xorg-server: X.Org X11 server - xorg-server-lts-quantal: X.Org X11 server - xorg-server-lts-raring: X.Org X11 server Details: Pedro Ribeiro discovered that the X.Org X server incorrectly handled memory operations when handling ImageText requests. 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) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 13.04: Ubuntu 12.10: Ubuntu 12.04 LTS: After a standard system update you need to reboot your computer to make all the necessary changes.
