CVE-2007-4103

https://notcve.org/view.php?id=CVE-2007-4103

The IAX2 channel driver (chan_iax2) in Asterisk Open 1.2.x before 1.2.23, 1.4.x before 1.4.9, and Asterisk Appliance Developer Kit before 0.6.0, when configured to allow unauthenticated calls, allows remote attackers to cause a denial of service (resource exhaustion) via a flood of calls that do not complete a 3-way handshake, which causes an ast_channel to be allocated but not released. El controlador de canal IAX2 (chan_iax2) de Asterisk Open 1.2.x anterior a 1.2.23, 1.4.x anterior a 1.4.9, y Asterisk Appliance Developer Kit anterior a 0.6.0, cuando está configurado para permitir llamadas no autenticadas, permite a atacantes remotos provocar una denegación de servicio (agotamiento de recursos) mediante una inundación de llamadas que no completan la negociación de 3 pasos, lo cual provoca que se reserve un canal ast_channel pero no se libere. • http://bugs.gentoo.org/show_bug.cgi?id=185713 http://ftp.digium.com/pub/asa/ASA-2007-018.pdf http://osvdb.org/38197 http://secunia.com/advisories/26274 http://secunia.com/advisories/29051 http://security.gentoo.org/glsa/glsa-200802-11.xml http://securityreason.com/securityalert/2960 http://www.securityfocus.com/archive/1/475069/100/0/threaded http://www.securityfocus.com/bid/24950 http://www.securitytracker.com/id?1018472 http://www.vupen.com/english/advisories/ • CWE-772: Missing Release of Resource after Effective Lifetime •
