Description Jan Lieskovsky 2012-03-16 07:41:47 EDT
A stack-based buffer overflow flaw was found in the way Asterisk Manager Interface of Asterisk, open source telephony toolkit, performed processing of certain HTTP Digest Authentication headers. A remote attacker, attempting to connect to the HTTP session could send a HTTP Digest Authentication header with specially-crafted values for certain fields, which once processed by the Asterisk parse digest authorization header functionality would lead to asterisk crash, or, potentially arbitrary code execution with the privileges of the user running the application.
