Multiple Cisco products contain vulnerabilities in the processing of Session Initiation Protocol (SIP) INVITE messages. These vulnerabilities were identified by the University of Oulu Secure Programming Group (OUSPG) "PROTOS" Test Suite for SIP and can be repeatedly exploited to produce a denial of service.

 It is possible to make the remote IOS crash by sending malformed SIP packets. These vulnerabilities are documented as CISCO bug id CSCdz39284 and CSCdz41124.
