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 1.8.x prior to 126.96.36.199. It, therefore,
could be affected by a denial of service vulnerability.
If a remote attacker initiates a SIP call and the recipient picks up,
the remote user can reply with a malformed Contact header that will
cause Asterisk to crash.
