"The remote host is affected by the vulnerability described in GLSA-200905-01
(Asterisk: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in the IAX2 channel
    driver when performing the 3-way handshake (CVE-2008-1897), when
    handling a large number of POKE requests (CVE-2008-3263), when handling
    authentication attempts (CVE-2008-5558) and when handling firmware
    download (FWDOWNL) requests (CVE-2008-3264). Asterisk does also not
    correctly handle SIP INVITE messages that lack a 'From' header
    (CVE-2008-2119), and responds differently to a failed login attempt
    depending on whether the user account exists (CVE-2008-3903,
    CVE-2009-0041).
  
Impact :

    Remote unauthenticated attackers could send specially crafted data to
    Asterisk, possibly resulting in a Denial of Service via a daemon crash,
    call-number exhaustion, CPU or traffic consumption. Remote
    unauthenticated attackers could furthermore enumerate valid usernames
    to facilitate brute-force login attempts.
  
Workaround :

    There is no known workaround at this time."

"Several vulnerabilities have been discovered in asterisk, an Open
Source PBX and telephony toolkit. The Common Vulnerabilities and
Exposures project identifies the following problems :

  - CVE-2009-0041
    It is possible to determine valid login names via
    probing, due to the IAX2 response from asterisk
    (AST-2009-001).

  - CVE-2008-3903
    It is possible to determine a valid SIP username, when
    Digest authentication and authalwaysreject are enabled
    (AST-2009-003).

  - CVE-2009-3727
    It is possible to determine a valid SIP username via
    multiple crafted REGISTER messages (AST-2009-008).

  - CVE-2008-7220 CVE-2007-2383
    It was discovered that asterisk contains an obsolete
    copy of the Prototype JavaScript framework, which is
    vulnerable to several security issues. This copy is
    unused and now removed from asterisk (AST-2009-009).

  - CVE-2009-4055
    It was discovered that it is possible to perform a
    denial of service attack via RTP comfort noise payload
    with a long data length (AST-2009-010).

The current version in oldstable is not supported by upstream anymore
and is affected by several security issues. Backporting fixes for
these and any future issues has become unfeasible and therefore we
need to drop our security support for the version in oldstable. We
recommend that all asterisk users upgrade to the stable distribution
(lenny)."
