Description

<em style='font-weight:bold;'>(Description Provided by <a href="http://cve.mitre.org/cgi-bin/cvename.cgi?name=2007-4103" target="_blank">CVE</a>)</em> : The IAX2 channel driver (chan_iax2) in Asterisk Open 1.2.x before 1.2.23, 1.4.x before 1.4.9, and Asterisk Appliance Developer Kit before 0.6.0, when configured to allow unauthenticated calls, allows remote attackers to cause a denial of service (resource exhaustion) via a flood of calls that do not complete a 3-way handshake, which causes an ast_channel to be allocated but not released.
