A vulnerability, which was classified as critical, was found in XFree86 and X11 (Windowing System Software). Affected is the function SProcRRConfigureOutputProperty. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The RandR extension in XFree86 4.2.0, X.Org X Window System (aka X11 or X) X11R6.7, and X.Org Server (aka xserver and xorg-server) before 1.16.3 allows remote authenticated users to cause a denial of service (out-of-bounds read or write) or possibly execute arbitrary code via a crafted length or index value to the (1) SProcRRQueryVersion, (2) SProcRRGetScreenInfo, (3) SProcRRSelectInput, or (4) SProcRRConfigureOutputProperty function.

The weakness was disclosed 12/10/2014 by Ilja van Sprundel (Website). The advisory is available at x.org. This vulnerability is traded as CVE-2014-8101 since 10/10/2014.
