CVE-2012-3863 asterisk: Possible resource leak on uncompleted re-invite transactions
Last modified: 2012-12-11 04:04:40 EST
If Asterisk sends a re-invite and an endpoint responds to the re-invite with a provisional response but never sends a final response, then the SIP dialog structure is never freed and the RTP ports for the call are never released. If an attacker has the ability to place a call, they could create a denial of service by using all available RTP ports.
