Clam AntiVirus ClamAV before 0.90 does not close open file descriptors under certain conditions, which allows remote attackers to cause a denial of service (file descriptor consumption and failed scans) via CAB archives with a cabinet header record length of zero, which causes a function to return without closing a file descriptor. Clam AntiVirus ClamAV anterior a 0.90 no cierra los descriptores de apertura de ficheros bajo ciertas condiciones, lo cual permite a atacantes remotos provocar denegación de servicio (consumo del descriptor de fichero y fallo de escaneo) a través de archivos CAB con una longitud de registro con una cabecera cabinet(.CAB) de cero, lo cual provoca que una función retorne sin cerrar el descriptor de fichero. • http://docs.info.apple.com/article.html?artnum=307562 http://labs.idefense.com/intelligence/vulnerabilities/display.php?id=475 http://lists.apple.com/archives/security-announce/2008/Mar/msg00001.html http://lists.suse.com/archive/suse-security-announce/2007-Feb/0004.html http://osvdb.org/32283 http://secunia.com/advisories/24183 http://secunia.com/advisories/24187 http://secunia.com/advisories/24192 http://secunia.com/advisories/24319 http://secunia.com/advisories/24332 http:/&# • CWE-772: Missing Release of Resource after Effective Lifetime •
