Descriptions
Multiple buffer overflows in the (1) XvQueryAdaptors and (2) XvQueryEncodings functions in X.org libXrender before 0.9.10 allow remote X servers to trigger out-of-bounds write operations via vectors involving length fields.
Múltiples desbordamientos de búfer en las funciones (1) XvQueryAdaptors y (2) XvQueryEncodings en X.org libXrender en versiones anteriores a 0.9.10 permite a servidores remotos X desencadenar operaciones de escritura fuera de límites a través de vectores que involucran campos de longitud.
Tobias Stoeckmann discovered that libXrender incorrectly handled certain responses. An attacker could possibly use this issue to cause a denial of service, or possibly execute arbitrary code.
