______________________________________________________________________________

1) Problem Description and Brief Discussion

   This update fixes various bugs and some security issues in the SUSE Linux
   Enterprise 10 SP 3 kernel.

   Following security issues were fixed:
   CVE-2009-4536: drivers/net/e1000/e1000_main.c in the e1000 driver in the
   Linux kernel handles Ethernet frames that exceed the MTU by processing
   certain trailing payload data as if it were a complete frame, which
   allows remote attackers to bypass packet filters via a large packet with
   a crafted payload.

   CVE-2009-4538: drivers/net/e1000e/netdev.c in the e1000e driver in the
   Linux kernel does not properly check the size of an Ethernet frame that
   exceeds the MTU, which allows remote attackers to have an unspecified
   impact via crafted packets.

   CVE-2010-0007: Missing CAP_NET_ADMIN checks in the ebtables netfilter
   code might have allowed local attackers to modify bridge firewall
   settings.

2) Solution or Work-Around

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

3) Special Instructions and Notes

   Please reboot the machine after installing the update.

4) Package Location and Checksums

   The preferred method for installing security updates is to use the YaST
   Online Update (YOU) tool. YOU detects which updates are required and
   automatically performs 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.

   Our maintenance customers are notified individually. The packages are
   offered for installation from the maintenance web:

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.
