FreeBSD : asterisk -- Crash in PJSIP resource when missing a contact header (2a3bc6ac-e7c6-11e7-a90b-001999f8d30b)

Medium Nessus Plugin ID 105448

Synopsis

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

Description

The Asterisk project reports :

A select set of SIP messages create a dialog in Asterisk. Those SIP messages must contain a contact header. For those messages, if the header was not present and using the PJSIP channel driver, it would cause Asterisk to crash. The severity of this vulnerability is somewhat mitigated if authentication is enabled. If authentication is enabled a user would have to first be authorized before reaching the crash point.

Solution

Update the affected package.
