(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).
    Chris
    Clark and Zane Lackey (iSEC Partners) reported a NULL pointer
    dereference in the IAX2 channel driver (chan_iax2)
    (CVE-2007-3763).
    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).
  
Impact :

    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.
  
Workaround :

    There is no known workaround at this time."
