______________________________________________________________________________

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-2009-3547: A race condition during pipe open could be used by
   local attackers to elevate privileges.

   CVE-2009-3238: The get_random_int function in drivers/char/random.c in
   the Linux kernel produces insufficiently random numbers, which allows
   attackers to predict the return value, and possibly defeat protection
   mechanisms based on randomization, via vectors that leverage the
   functions tendency to return the same value over and over again for
   long stretches of time.

   CVE-2009-1192: The (1) agp_generic_alloc_page and (2)
   agp_generic_alloc_pages functions in drivers/char/agp/generic.c in
   the agp subsystem in the Linux kernel do not zero out pages that may
   later be available to a user-space process, which allows local users
   to obtain sensitive information by reading these pages.

   CVE-2009-2909: Unsigned check in the ax25 socket handler could allow
   local attackers to potentially crash the kernel or even execute code.

   CVE-2009-2910: On x86_64 systems a information leak of high register
   contents (upper 32bit) was fixed.

2) Solution or Work-Around

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

3) Special Instructions and Notes

   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 <file.rpm>

   to apply the update, replacing <file.rpm> with the filename of the
   downloaded RPM package.

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

5) Pending Vulnerabilities, Solutions, and Work-Arounds:

   - Pending kernel updates for the CVE-2009-3547 issue.

     SLES 9 kernels are still in QA and were delayed to build failures. We expect
     a release either tomorrow or Monday.

     SUSE Linux Enterprise 11 and the openSUSE products use
     "mmap_min_addr" protection by default and are default not vulnerable.
     The fix will be rolled in into their next update rounds.
______________________________________________________________________________

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 <file>

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

      gpg: Signature made <DATE> using RSA key ID 3D25D3D9
      gpg: Good signature from "SuSE Security Team <security@suse.de>"

    where <DATE> 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 <file.rpm>

    to verify the signature of the package, replacing <file.rpm> 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+subscribe@opensuse.org>.

    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
                <opensuse-security-announce+subscribe@opensuse.org>.

    =====================================================================
    SUSE's security contact is <security@suse.com> or <security@suse.de>.
