A telephony application running on the remote host is affected by a
denial of service vulnerability.
According to the version in its SIP banner, the version of Asterisk
running on the remote host is potentially affected by a vulnerability
that could allow a remote, authenticated attacker to exhaust the
server of resources.
If an endpoint sends a provisional response to the server's re-INVITE
message, certain data structures are not freed. More iterations of
this sequence lead to exhaustion of all available RTP ports.
