______________________________________________________________________________

1) Problem Description and Brief Discussion

   The SUSE Linux Enterprise 10 Service Pack 2 kernel was updated to
   version 2.6.16.60-0.34 to fix some security issues and various bugs.

   The following security problems have been fixed:

   CVE-2008-5079: net/atm/svc.c in the ATM subsystem allowed local users
   to cause a denial of service (kernel infinite loop) by making two calls
   to svc_listen for the same socket, and then reading a /proc/net/atm/
   *vc file, related to corruption of the vcc table.

   CVE-2008-5029: The __scm_destroy function in net/core/scm.c makes
   indirect recursive calls to itself through calls to the fput function,
   which allows local users to cause a denial of service (panic) via
   vectors related to sending an SCM_RIGHTS message through a UNIX domain
   socket and closing file descriptors.

   CVE-2008-4933: Buffer overflow in the hfsplus_find_cat function in
   fs/hfsplus/catalog.c allowed attackers to cause a denial of service
   (memory corruption or system crash) via an hfsplus filesystem
   image with an invalid catalog namelength field, related to the
   hfsplus_cat_build_key_uni function.

   CVE-2008-5025: Stack-based buffer overflow in the hfs_cat_find_brec
   function in fs/hfs/catalog.c allowed attackers to cause a denial of
   service (memory corruption or system crash) via an hfs filesystem
   image with an invalid catalog namelength field, a related issue to
   CVE-2008-4933.

   CVE-2008-5182: The inotify functionality might allow local users to
   gain privileges via unknown vectors related to race conditions in
   inotify watch removal and umount.


   A lot of other bugs were fixed, a detailed list can be found in the
   RPM changelog.

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.

  - 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
                .
