Asterisk is an open source telephony engine and tool kit.
Multiple vulnerabilities have been found in Asterisk:
By sending a long voice or video RTP frame, a remote attacker could possibly execute arbitrary code on the target machine. Sending specially crafted LAGRQ or LAGRP frames containing information elements of IAX frames, or a certain data length value in a crafted packet, or performing a flood of calls not completing a 3-way handshake, could result in a Denial of Service.
There is no known workaround at this time.
All Asterisk users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/asterisk-1.2.17-r1"
