CVE-2014-2288

Status Candidate

Overview

The PJSIP channel driver in Asterisk Open Source 12.x before 12.1.1, when qualify_frequency "is enabled on an AOR and the remote SIP server challenges for authentication of the resulting OPTIONS request," allows remote attackers to cause a denial of service (crash) via a PJSIP endpoint that does not have an associated outgoing request.

Asterisk Project Security Advisory - AST-2014-003
Posted Mar 11, 2014
Authored by Joshua Colp | Site asterisk.org

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.
