The remote server is affected by two buffer overflow vulnerabilities.
The version of Asterisk installed on the remote host contains two
stack-based buffer overflows in its SIP SDP handler when attempting to
read the 'T38FaxRateManagement:' and 'T38FaxUdpEC:' options in the SDP
within a SIP packet. An unauthenticated, remote attacker may be able
to leverage this flaw to execute code on the affected host subject to
the privileges under which Asterisk runs.

Either disable T.38 support or upgrade to Asterisk 1.4.3 / AsteriskNow
Beta 6 or later.
