The IAX2 channel driver (chan_iax2) for Asterisk 1.2.x before 1.2.9 and 1.0.x before 1.0.11 allows remote attackers to cause a denial of service (crash) and execute arbitrary code via truncated IAX 2 (IAX2) video frames, which bypasses a length check and leads to a buffer overflow involving negative length check. NOTE: the vendor advisory claims that only a DoS is possible, but the original researcher is reliable. • http://secunia.com/advisories/20497 http://secunia.com/advisories/20658 http://secunia.com/advisories/20899 http://secunia.com/advisories/21222 http://securitytracker.com/id?1016236 http://www.asterisk.org/node/95 http://www.debian.org/security/2006/dsa-1126 http://www.gentoo.org/security/en/glsa/glsa-200606-15.xml http://www.novell.com/linux/security/advisories/2006_38_security.html http://www.securityfocus.com/archive/1/436127/100/0/threaded http://www.securityfoc • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
