https://notcve.org/view.php?id=CVE-2009-1255

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. • http://archives.neohapsis.com/archives/fulldisclosure/2009-04/0282.html http://code.google.com/p/memcachedb/source/browse/trunk/ChangeLog?spec=svn98&r=98 http://code.google.com/p/memcachedb/source/detail?r=98 http://code.google.com/p/memcachedb/source/diff?spec=svn98&r=98&format=side&path=/trunk/memcachedb.c http://groups.google.com/group/memcached/browse_thread/thread/ff96a9b88fb5d40e http://osvdb.org/54127 http://secunia.com/advisories/34915 http://secunia.com/advisories/34932 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
