A telephony application running on the remote host is affected by
multiple buffer overflow vulnerabilities.
The version of Asterisk running 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.
See also :
Either disable T.38 support or upgrade to Asterisk 1.4.3 / AsteriskNow
Beta 6 or later.
