CVE-2013-1872

Los controladores Intel en Mesa 8.0.x y 9.0.x, permiten a atacantes dependientes del contexto provocar una denegación de servicio (caída y afirmación accesible) y posiblemente la ejecución de código arbitrario a través de vectores que involucran a los gráficos 3D que provocar un acceso a una matriz fuera de rango, relacionado con la función fs_visitor::remove_dead_constants. NOTA: esta vulnerabilidad podría estar relacionada con el CVE-2013-0796.

Mesa provides a 3D graphics API that is compatible with Open Graphics Library. It also provides hardware-accelerated drivers for many popular graphics chips. An out-of-bounds access flaw was found in Mesa. If an application using Mesa exposed the Mesa API to untrusted inputs, an attacker could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. It was found that Mesa did not correctly validate messages from the X server. A malicious X server could cause an application using Mesa to crash or, potentially, execute arbitrary code with the privileges of the user running the application.
