CVE Name CVE-2014-4045
Description A remotely exploitable crash vulnerability exists in the
PJSIP channel driver's pub/sub framework. If an attempt is
made to unsubscribe when not currently subscribed and the
endpoint's "sub_min_expiry" is set to zero, Asterisk tries
to create an expiration timer with zero seconds, which is
not allowed, so an assertion raised.
Resolution Upgrade to a version with the patch integrated, apply the
patch, or make sure the "sub_min_expiry" endpoint
configuration option is greater than zero.
