FreeBSD : asterisk -- Remotely triggered crash (e60d9e65-3f6b-11e4-ad16-001999f8d30b)

Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

The Asterisk project reports :

When an out of call message - delivered by either the SIP or PJSIP
channel driver or the XMPP stack - is handled in Asterisk, a crash can
occur if the channel servicing the message is sent into the ReceiveFax
dialplan application while using the res_fax_spandsp module.

Note that this crash does not occur when using the res_fax_digium
module. While this crash technically occurs due to a configuration
issue, as attempting to receive a fax from a channel driver that only
contains textual information will never succeed, the likelihood of
having it occur is sufficiently high as to warrant this advisory.
