A vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Cerulean Studios Trillian Pro. Authentication is not required to exploit this vulnerability. The specific flaw exists in the Rendezvous / XMPP (Extensible Messaging and Presence Protocol) messaging subsystem. Trillian locates nearby users through the ‘_presence’ mDNS (multicast DNS) service on UDP port 5353. Once a user is registered through mDNS, messaging is accomplished via XMPP over TCP port 5298.
