CVSS: 5.0EPSS: 95%CPEs: 36EXPL: 1CVE-2007-3763 – Asterisk < 1.2.22/1.4.8 - IAX2 Channel Driver Remote Crash
https://notcve.org/view.php?id=CVE-2007-3763
The IAX2 channel driver (chan_iax2) in Asterisk before 1.2.22 and 1.4.x before 1.4.8, Business Edition before B.2.2.1, AsteriskNOW before beta7, Appliance Developer Kit before 0.5.0, and s800i before 1.0.2 allows remote attackers to cause a denial of service (crash) via a crafted (1) LAGRQ or (2) LAGRP frame that contains information elements of IAX frames, which results in a NULL pointer dereference when Asterisk does not properly set an associated variable. El gestor de dispositivo de canal IAX2 (chan_iax2) en Asterisk versiones anteriores a 1.2.22 y 1.4.x versiones anteriores a 1.4.8, Business Edition versiones anteriores a B.2.2.1, AsteriskNOW versiones anteriores a beta7, Appliance Developer Kit versiones anteriores a 0.5.0, y s800i versiones anteriores a 1.0.2 permite a atacantes remotos provocar una denegación de servicio (caída) mediante tramas (1) LAGRQ ó (2) LAGRP que contienen elementos de información de tramas IAX, que resulta en una referencia a puntero NULL cuando Asterisk no asigna apropiadamente una variable asociado. • https://www.exploit-db.com/exploits/4249 http://bugs.gentoo.org/show_bug.cgi?id=185713 http://ftp.digium.com/pub/asa/ASA-2007-015.pdf http://secunia.com/advisories/26099 http://secunia.com/advisories/29051 http://security.gentoo.org/glsa/glsa-200802-11.xml http://www.debian.org/security/2007/dsa-1358 http://www.novell.com/linux/security/advisories/2007_15_sr.html http://www.securityfocus.com/bid/24950 http://www.securitytracker.com/id?1018407 http://www •
