Descriptions

Heap-based buffer overflow in ultra.c in LibVNCClient in LibVNCServer before 0.9.11 allows remote servers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted FramebufferUpdate message with the Ultra type tile, such that the LZO payload decompressed length exceeds what is specified by the tile dimensions.

Desbordamiento de búfer basado en memoria dinámica en ultra.c en LibVNCClient en LibVNCServer en versiones anteriores a 0.9.11 permite a servidores remotos provocar una denegación de servicio (caída de aplicación) o posiblemente ejecutar código arbitrario a través de un mensaje FramebufferUpdate manipulado con el título de tipo Ultra, de manera que la longitud de la carga útil LZO descomprimida excede lo especificado por las dimensiones del azulejo.
