Descriptions

Asterisk Open Source 1.0.x and 1.2.x before 1.2.29 and Business Edition A.x.x and B.x.x before B.2.5.3, when pedantic parsing (aka pedanticsipchecking) is enabled, allows remote attackers to cause a denial of service (daemon crash) via a SIP INVITE message that lacks a From header, related to invocations of the ast_uri_decode function, and improper handling of (1) an empty const string and (2) a NULL pointer.

Asterisk Open Source 1.0.x y 1.2.x anterior 1.2.29 y Business Edition A.x.x y B.x.x anterior B.2.5.3, cuando "pedantic parsing" (también conocido como pedanticsipchecking) está activado, permite a atacantes remotos provocar una denegación de servicio (caída de demonio) a través de un mensaje SIP INVITE que carece de una cabecera From, relacionado con la invocación de la función ast_uri_decode y el manejo incorrecto de (1) una cadena const vacía y (2) un puntero NULL.
