The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200802-11
(Asterisk: Multiple vulnerabilities)
Multiple vulnerabilities have been found in Asterisk:
Russel Bryant reported a stack-based buffer overflow in the IAX2 channel
driver (chan_iax2) when bridging calls between chan_iax2 and any
channel driver that uses RTP for media (CVE-2007-3762).
Clark and Zane Lackey (iSEC Partners) reported a NULL pointer
dereference in the IAX2 channel driver (chan_iax2)
Will Drewry (Google Security) reported a
vulnerability in the Skinny channel driver (chan_skinny), resulting in
an overly large memcpy (CVE-2007-3764).
Will Drewry (Google
Security) reported a vulnerability in the IAX2 channel driver
(chan_iax2), that does not correctly handle unauthenticated
transactions using a 3-way handshake (CVE-2007-4103).
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.
