Description Jan Lieskovsky 2012-05-30 09:53:17 UTC
A denial of service flaw was found in the way Skinny protocol implementation / driver of the Asterisk, an open source telephony toolkit, performed SCCP connection close. An authenticated Asterisk user (with valid SCCP ID) could use this flaw to cause asterisk executable to crash (dereference NULL pointer) by closing the connection to the Asterisk server in certain call states ("Off hook" for example).
