Descriptions

Use-after-free vulnerability in the doImageText function in dix/dixfonts.c in the xorg-server module before 1.14.4 in X.Org X11 allows remote authenticated users to cause a denial of service (daemon crash) or possibly execute arbitrary code via a crafted ImageText request that triggers memory-allocation failure.

Vulnerabilidad de uso después de liberación en la función dolmageText en dix/dixfonts.c del módulo xorg-server anterior a la versión 1.14.4 en X.Org X11 permite a usuarios remotos autenticados provocar una denegación de servicio (cuelgue del demonio) o posiblemente ejecutar código arbitrario a través de una petición ImageText manipulada que provoque un fallo de reubicación de memoria.
