Description Jan Lieskovsky 2013-01-03 14:19:33 UTC 
Multiple stack-based buffer overflow flaws were found in the way Asterisk, the open-source PBX software, processed certain SIP, HTTP and XMPP protocol-based network messages. A remote attacker could use this flaw to cause asterisk executable to crash via specially-crafted SIP, HTTP or XMPP protocol messages.
