______________________________________________________________________________

1) Problem Description and Brief Discussion

   A remote Denial of Service vulnerability has been fixed in the BIND
   DNS nameserver.

   Specially crafted packets could cause bind servers (recursive as well
   as authoritative) to exit. (CVE-2011-2464)

   This issue affected bind 9.6 and later, so SUSE Linux Enterprise
   10 SP4, SUSE Linux Enterprise 11 SP1 and openSUSE 11.3 and 11.4
   were affected.

   Older service packs / products are not affected by CVE-2011-2464.


   Please also note that the other currently published security issue,
   CVE-2011-2465, affected only BIND versions 9.8.0 and later, which none
   of our current products include, making all of them not affected by
   this issue.

2) Solution or Work-Around

   There is no known workaround, please install the update packages.

3) Special Instructions and Notes

   The RPM update process should restart the named service automatically,
   but cross check if this happens and if it still correctly always as usual.

4) Package Location and Checksums

   The preferred method for installing security updates is to use the YaST
   "Online Update" module or the "zypper" commandline tool. The package and
   patch management stack will detect which updates are required and
   automatically perform the necessary steps to verify and install them.

   Alternatively, download the update packages for your distribution manually
   and verify their integrity by the methods listed in Section 6 of this
   announcement. Then install the packages using the command

     rpm -Fhv 

   to apply the update, replacing  with the filename of the
   downloaded RPM package.

6) Authenticity Verification and Additional Information

  - Announcement authenticity verification:

    SUSE security announcements are published via mailing lists and on Web
    sites. The authenticity and integrity of a SUSE security announcement is
    guaranteed by a cryptographic signature in each announcement. All SUSE
    security announcements are published with a valid signature.

    To verify the signature of the announcement, save it as text into a file
    and run the command

      gpg --verify 

    replacing  with the name of the file where you saved the
    announcement. The output for a valid signature looks like:

      gpg: Signature made  using RSA key ID 3D25D3D9
      gpg: Good signature from "SuSE Security Team "

    where  is replaced by the date the document was signed.

    If the security team's key is not contained in your key ring, you can
    import it from the first installation CD. To import the key, use the
    command

      gpg --import gpg-pubkey-3d25d3d9-36e12d04.asc

  - Package authenticity verification:

    SUSE update packages are available on many mirror FTP servers all over the
    world. While this service is considered valuable and important to the free
    and open source software community, the authenticity and the integrity of
    a package needs to be verified to ensure that it has not been tampered
    with.

    The internal rpm package signatures provide an easy way to verify the
    authenticity of an RPM package. Use the command

     rpm -v --checksig 

    to verify the signature of the package, replacing  with the
    filename of the RPM package downloaded. The package is unmodified if it
    contains a valid signature from build@suse.de with the key ID 9C800ACA.

    This key is automatically imported into the RPM database (on
    RPMv4-based distributions) and the gpg key ring of 'root' during
    installation. You can also find it on the first installation CD and at
    the end of this announcement.
