Asterisk Project Security Advisory - A remotely exploitable crash vulnerability exists in the PJSIP channel driver if the "qualify_frequency" configuration option is enabled on an AOR and the remote SIP server challenges for authentication of the resulting OPTIONS request. The response handling code wrongly assumes that a PJSIP endpoint will always be associated with an outgoing request which is incorrect.

CVE Name CVE-2014-2288

Description A remotely exploitable crash vulnerability exists in the
PJSIP channel driver if the "qualify_frequency"
configuration option is enabled on an AOR and the remote
SIP server challenges for authentication of the resulting
OPTIONS request. The response handling code wrongly assumes
that a PJSIP endpoint will always be associated with an
outgoing request which is incorrect.

Resolution This patch adds a check when handling responses challenging
for authentication. If no endpoint is associated with the
request no retry with authentication will occur.
