Created asterisk tracking bugs for this issue: Affects: fedora-all [bug 1374734] Affects: epel-6 [bug 1374735] UPDATE (20 October, 2016): It has been brought to our attention by Walter Doekes that this same leak can be exploited without the use of the overlap dialing feature. Sending SIP requests in a specific sequence outside the norm could also cause the leak of RTP resources. By sending an in-dialog INVITE after receiving a 404 response (but before sending an ACK), an attacker could cause the same leak to occur. I'm working with the Digium developers to get systemd support added to dahdi-tools, so that we can unretire dahdi-tools, which is a dependency of Asterisk. That will allow me to update the Asterisk packages in Fedora/EPEL to the latest version which will close this vulnerability. ARRAY(0x558ebd7dae40) |
