Detailsinfo

A vulnerability classified as critical was found in X.Org 6.8.2/6.9.0/7.0/7.1. Affected by this vulnerability is the function procdbegetvisualinfo of the component DBE Extension. The manipulation with an unknown input leads to a integer coercion vulnerability. The CWE definition for the vulnerability is CWE-192. Integer coercion refers to a set of flaws pertaining to the type casting, extension, or truncation of primitive data types. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Integer overflow in the ProcDbeGetVisualInfo function in the DBE extension for X.Org 6.8.2, 6.9.0, 7.0, and 7.1, and XFree86 X server, allows local users to execute arbitrary code via a crafted X protocol request that triggers memory corruption during processing of unspecified data structures.

The bug was discovered 01/09/2007. The weakness was shared 01/09/2007 by Sean Larsson (iDefense) with iDEFENSE Labs (Website). The advisory is shared at lists.freedesktop.org. This vulnerability is known as CVE-2006-6102 since 11/24/2006. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are known, but no exploit is available.
