Description Murray McAllister 2014-03-11 04:58:39 UTC

A remote denial of service flaw was found in Asterisk. This could be used to cause Asterisk to hit the open file descriptor limit, preventing it from handling further requests. The upstream advisory (http://downloads.asterisk.org/pub/security/AST-2014-002.html) notes the attacker requires "Valid account credentials or anonymous dial in" and "A valid extension that can be dialed from the SIP account".

This issue affected all 1.8.x and 11.x versions. It has been corrected in versions 1.8.26.1 and 11.8.1.
