Detailsinfo

A vulnerability was found in XFree86 and X11 (Windowing System Software) (the affected version is unknown) and classified as critical. This issue affects the function ProcDRI2GetBuffers. The manipulation with an unknown input leads to a integer overflow vulnerability. Using CWE to declare the problem leads to CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Integer overflow in the ProcDRI2GetBuffers function in the DRI2 extension in X.Org Server (aka xserver and xorg-server) 1.7.0 through 1.16.x before 1.16.3 allows remote authenticated users to cause a denial of service (crash) or possibly execute arbitrary code via a crafted request, which triggers an out-of-bounds read or write.

The weakness was published 12/10/2014 by Ilja van Sprundel with IOActive (Website). It is possible to read the advisory at x.org. The identification of this vulnerability is CVE-2014-8094 since 10/10/2014. The exploitation is known to be easy. The attack may be initiated remotely.
