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/ •

https://notcve.org/view.php?id=CVE-2007-1306
Asterisk 1.4 before 1.4.1 and 1.2 before 1.2.16 allows remote attackers to cause a denial of service (crash) by sending a Session Initiation Protocol (SIP) packet without a URI and SIP-version header, which results in a NULL pointer dereference. Asterisk versiones 1.4 anteriores a 1.4.1 y versiones 1.2 anteriores a 1.2.16, permite a atacantes remotos causar una denegación de servicio (bloqueo) enviando un paquete de Session Initiation Protocol (SIP) sin una URI y Encabezado SIP-version, lo que resulta en una desreferencia del puntero NULL. • https://www.exploit-db.com/exploits/3407 http://asterisk.org/node/48319 http://asterisk.org/node/48320 http://labs.musecurity.com/advisories/MU-200703-01.txt http://secunia.com/advisories/24380 http://secunia.com/advisories/24578 http://secunia.com/advisories/25582 http://security.gentoo.org/glsa/glsa-200703-14.xml http://www.debian.org/security/2007/dsa-1358 http://www.kb.cert.org/vuls/id/228032 http://www.novell.com/linux/security/advisories/2007_34_asterisk •

Integer overflow in the get_input function in the Skinny channel driver (chan_skinny.c) in Asterisk 1.0.x before 1.0.12 and 1.2.x before 1.2.13, as used by Cisco SCCP phones, allows remote attackers to execute arbitrary code via a certain dlen value that passes a signed integer comparison and leads to a heap-based buffer overflow. Desbordamiento de entero en la función get_input en el controlador de canal Skinny (chan_skinny.c) en Asterisk 1.0.x anteriores a 1.0.12 y 1.2.x anteriores a 1.2.13, utilizados en los teléfonos Cisco SCCP, permite a atacantes remotos ejecutar código de su elección mediante un cierto valor dlen que pasa una comparación de entero con signo y lleva a un desbordamiento de búfer basado en montón. • https://www.exploit-db.com/exploits/2597 http://ftp.digium.com/pub/asterisk/releases/ChangeLog-1.0.12 http://ftp.digium.com/pub/asterisk/releases/ChangeLog-1.2.13 http://lists.grok.org.uk/pipermail/full-disclosure/2006-October/050171.html http://secunia.com/advisories/22480 http://secunia.com/advisories/22651 http://secunia.com/advisories/22979 http://secunia.com/advisories/23212 http://securitytracker.com/id?1017089 http://www.asterisk.org/node/109 http://www.gent •

Unspecified vulnerability in the SIP channel driver (channels/chan_sip.c) in Asterisk 1.2.x before 1.2.13 and 1.4.x before 1.4.0-beta3 allows remote attackers to cause a denial of service (resource consumption) via unspecified vectors that result in the creation of "a real pvt structure" that uses more resources than necessary. Vulnerabilidad no especificada en el controlador de canal SIP (channels/chan_sip.c) en ASterisk 1.2.x anteriores a 1.2.13 y 1.4.x aneriores a 1.4.0-beta3 permite a atacantes remotos provocar una denegación de servicio (agotamiento de recursos) a través de vectores no especificados que resultan en la creación de una "estructura pvt real" que usa más recursos de los necesarios. • http://ftp.digium.com/pub/asterisk/releases/ChangeLog-1.2.13 http://secunia.com/advisories/22651 http://secunia.com/advisories/22979 http://www.asterisk.org/node/109 http://www.asterisk.org/node/110 http://www.gentoo.org/security/en/glsa/glsa-200610-15.xml http://www.novell.com/linux/security/advisories/2006_69_asterisk.html http://www.osvdb.org/29973 http://www.securityfocus.com/archive/1/449183/100/0/threaded http://www.securityfocus.com/bid/20835 http: •
