The http-index-format MIME type parser (nsDirIndexParser) in Firefox 3.x before 3.0.4, Firefox 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 does not check for an allocation failure, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via an HTTP index response with a crafted 200 header, which triggers memory corruption and a buffer overflow. El analizador de tipo http-index-format MIME (nsDirIndexParser) en Firefox 3.x antes de 3.0.4, Firefox 2.x antes de 2.0.0.18 y SeaMonkey 1.x antes de 1.1.13 no comprueba un fallo de almacenamiento, lo que permite a atacantes remotos provocar una denegación de servicio (caída) y posiblemente ejecutar código de su elección mediante una respuesta de índice HTTP con una cabecera 200 manipulada, lo que dispara corrupción de memoria y un desbordamiento de búfer. • http://lists.opensuse.org/opensuse-security-announce/2008-11/msg00004.html http://secunia.com/advisories/32684 http://secunia.com/advisories/32693 http://secunia.com/advisories/32694 http://secunia.com/advisories/32695 http://secunia.com/advisories/32713 http://secunia.com/advisories/32714 http://secunia.com/advisories/32721 http://secunia.com/advisories/32778 http://secunia.com/advisories/32845 http://secunia.com/advisories/32853 http://secunia.com/advisories/33433 http:// • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
