The Manager Interface in Asterisk before 1.2.18 and 1.4.x before 1.4.3 allows remote attackers to cause a denial of service (crash) by using MD5 authentication to authenticate a user that does not have a password defined in manager.conf, resulting in a NULL pointer dereference. El Manager Interface en Asterisk anterior a 1.2.18 y 1.4.x anterior a 1.4.3 permite a atacantes remotos provocar denegación de servicio (caida) utilizando validación MD5 para validar a un usuario que no tiene definida una contraseña en manager.conf, dando como resultado un puntero no referencia NULL. • http://secunia.com/advisories/24977 http://secunia.com/advisories/25582 http://securityreason.com/securityalert/2646 http://www.asterisk.org/files/ASA-2007-012.pdf http://www.debian.org/security/2007/dsa-1358 http://www.novell.com/linux/security/advisories/2007_34_asterisk.html http://www.osvdb.org/35369 http://www.securityfocus.com/archive/1/466911/100/0/threaded http://www.securityfocus.com/bid/23649 http://www.securitytracker.com/id?1017955 http://www.vupen.com/ •
