Description Jan Lieskovsky 2012-04-24 13:41:15 UTC

A denial of service (asterisk crash) was found in the way Session Initiation Protocol (SIP) channel implementation (SIP driver) of the Asterisk, an open-source telephony toolkit processed certain SIP UPDATE requests, when the 'trustrpid' option was enabled. A remote attacker, able to properly time the SIP update request arrival, [it to come within (after call was terminated and associated channel object has been destroyed,  but before SIP dialog associated with the call has been destroyed) interval] could use this flaw to cause asterisk executable crash.
