Detail

Ilja van Sprundel of IOActive discovered several security issues in the X.org X server, which may lead to privilege escalation or denial of service.

For the stable distribution (wheezy), these problems have been fixed in version 1.12.4-6+deb7u5.

For the upcoming stable distribution (jessie), these problems will be fixed soon.

For the unstable distribution (sid), these problems have been fixed in version 2:1.16.2.901-1.

We recommend that you upgrade your xorg-server packages.

Title: RHSA-2014:1982 -- xorg-x11-server security update (Important)
Description: X.Org is an open source implementation of the X Window System. It provides the basic low-level functionality that full-fledged graphical user interfaces are designed upon. Multiple integer overflow flaws and out-of-bounds write flaws were found in the way the X.Org server calculated memory requirements for certain X11 core protocol and GLX extension requests. A malicious, authenticated client could use either of these flaws to crash the X.Org server or, potentially, execute arbitrary code with root privileges. (CVE-2014-8092, CVE-2014-8093, CVE-2014-8098) It was found that the X.Org server did not properly handle SUN-DES-1 (Secure RPC) authentication credentials. A malicious, unauthenticated client could use this flaw to crash the X.Org server by submitting a specially crafted authentication request. (CVE-2014-8091) Multiple out-of-bounds access flaws were found in the way the X.Org server calculated memory requirements for certain requests. A malicious, authenticated client could use either of these flaws to crash the X.Org server, or leak memory contents to the client. (CVE-2014-8097) Multiple out-of-bounds access flaws were found in the way the X.Org server calculated memory requirements for certain requests. A malicious, authenticated client could use either of these flaws to crash the X.Org server. (CVE-2014-8095, CVE-2014-8096, CVE-2014-8099, CVE-2014-8100, CVE-2014-8101, CVE-2014-8102) All xorg-x11-server users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.
