The Presence Engine (PE) service in Cisco Unified Presence 6.x before 6.0(7) and 7.x before 7.0(8) does not properly handle an erroneous Contact field in the header of a SIP SUBSCRIBE message, which allows remote attackers to cause a denial of service (process failure) via a malformed message, aka Bug ID CSCtd39629.
