The Asterisk Development Team has announced security releases for Asterisk as

The releases of Asterisk 1.6.0.22, 1.6.1.14, and 1.6.2.2 include the fix
described in security advisory AST-2010-001.

The issue is that an attacker attempting to negotiate T.38 over SIP can remotely
crash Asterisk by modifying the FaxMaxDatagram field of the SDP to contain
either a negative or exceptionally large value.  The same crash will occur when
the FaxMaxDatagram field is omitted from the SDP, as well.

For more information about the details of this vulnerability, please read the
security advisory AST-2009-009, which was released at the same time as this
announcement.
