Descriptions

The process_stat function in (1) Memcached before 1.2.8 and (2) MemcacheDB 1.2.0 discloses (a) the contents of /proc/self/maps in response to a stats maps command and (b) memory-allocation statistics in response to a stats malloc command, which allows remote attackers to obtain sensitive information such as the locations of memory regions, and defeat ASLR protection, by sending a command to the daemon's TCP port.

La función process_stat en (1) Memcached antes de v1.2.8 y (2) MemcacheDB v1.2.0 revela (a) el contenido de /proc/self/maps en respuesta a un comando stats maps (estadisticas de mapas) y (b) las estadísticas de la asignación de memoria en respuesta a un comando stats malloc (estadisticas de asignacion de memoria), lo cual permite a atacantes remotos obtener información sensible como la localización de regiones de memoria, y evitar la protección ASLR, mediante el envío de un comando a el demonio del puerto TCP.

The process_stat function in Memcached prior 1.2.8 discloses memory-allocation statistics in response to a stats malloc command, which allows remote attackers to obtain potentially sensitive information by sending a command to the daemon's TCP port. The updated packages have been patched to prevent this.
