______________________________________________________________________________

1) Problem Description and Brief Discussion

   This update of the SUSE Linux Enterprise 11 SP1 fixes three critical
   security issues and some bugs.

   Following security issues were fixed:
   CVE-2010-3904: A local privilege escalation in RDS sockets allowed
   local attackers to gain root privileges.

   CVE-2010-2963: A problem in the compat ioctl handling in video4linux
   allowed local attackers with a video device plugged in to gain root
   privileges on x86_64 systems.

   Please note that the net/rds socket protocol module only lives in the
   -extra kernel package, which is not installed by default on the SUSE
   Linux Enterprise Server 11.

   CVE-2010-2963: A problem in the compat ioctl handling in video4linux
   allowed local attackers with a video device plugged in to gain
   privileges on x86_64 systems.

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" 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.

   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.

  - SUSE runs two security mailing lists to which any interested party may
    subscribe:

    opensuse-security@opensuse.org
        -   General Linux and SUSE security discussion.
            All SUSE security announcements are sent to this list.
            To subscribe, send an e-mail to
                .

    opensuse-security-announce@opensuse.org
        -   SUSE's announce-only mailing list.
            Only SUSE's security announcements are sent to this list.
            To subscribe, send an e-mail to
                .
