Descriptions
The SIP process in Cisco Unified Communications Manager (aka CUCM, formerly CallManager) 7.x before 7.1(5b)su4 and 8.x before 8.0(1) does not properly handle SDP data within a SIP call in certain situations related to use of the g729ar8 codec for a Media Termination Point (MTP), which allows remote attackers to cause a denial of service (service outage) via a crafted call, aka Bug ID CSCtc61990.
El proceso SIP en Cisco Unified Communications Manager (también conocido como CUCM o CallManager) v7.x antes de v7.1(5b)su4 y v8.x antes de v8.0(1), no maneja adecuadamente datos SDP entre una llamada SIP en ciertas situaciones relacionadas con el uso del codec g729ar8 para Media Termination Point (MTP), lo que permite a atacantes remotos provocar una denegación de servicio (interrupción del servicio) a través de una llamada modificada, también conocido como Bug ID CSCtc61990.
