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.

CVE-2012-3812 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-3812):
  Double free vulnerability in apps/app_voicemail.c in Asterisk Open Source
  1.8.x before and 10.x before 10.5.2, Certified Asterisk
  1.8.11-certx before 1.8.11-cert4, and Asterisk Digiumphones
  10.x.x-digiumphones before 10.5.2-digiumphones allows remote authenticated
  users to cause a denial of service (daemon crash) by establishing multiple
  voicemail sessions and accessing both the Urgent mailbox and the INBOX

CVE-2012-3863 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-3863):
  channels/chan_sip.c in Asterisk Open Source 1.8.x before and 10.x
  before 10.5.2, Asterisk Business Edition C.3.x before C.3.7.5, Certified
  Asterisk 1.8.11-certx before 1.8.11-cert4, and Asterisk Digiumphones
  10.x.x-digiumphones before 10.5.2-digiumphones does not properly handle a
  provisional response to a SIP reINVITE request, which allows remote
  authenticated users to cause a denial of service (RTP port exhaustion) via
  sessions that lack final responses.
