1) Problem Description and Brief Discussion

   This security update of the SUSE Linux Enterprise 11 GA and openSUSE
   11.1 kernel updates the kernel to 2.6.27.54 and fixes various security
   issues and other bugs.

   The SUSE Linux Enterprise Server 11 kernel was released last week,
   the openSUSE 11.1 kernel with the same source base yesterday.

   Following security issues were fixed:
   CVE-2010-3310: Multiple integer signedness errors in net/rose/af_rose.c
   in the Linux kernel allowed local users to cause a denial of service
   (heap memory corruption) or possibly have unspecified other impact
   via a rose_getname function call, related to the rose_bind and
   rose_connect functions.

   CVE-2010-2955: A kernel information leak via the WEXT ioctl was fixed.

   CVE-2010-3080: A double free in an alsa error path was fixed, which
   could lead to kernel crashes.

   CVE-2010-3078: Fixed a kernel information leak in the xfs filesystem.

   CVE-2010-3296: Fixed a kernel information leak in the cxgb3 driver.

   CVE-2010-3297: Fixed a kernel information leak in the net/eql driver.

   CVE-2010-2954: The irda_bind function in net/irda/af_irda.c in the
   Linux kernel did not properly handle failure of the irda_open_tsap
   function, which allowed local users to cause a denial of service
   (NULL pointer dereference and panic) and possibly have unspecified
   other impact via multiple unsuccessful calls to bind on an AF_IRDA
   (aka PF_IRDA) socket.

   CVE-2010-2946: The 'os2' xattr namespace on the jfs filesystem could
   be used to bypass xattr namespace rules.

   CVE-2010-2942: Fixed a kernel information leak in the net scheduler
   code.

   CVE-2010-3015: Integer overflow in the ext4_ext_get_blocks function
   in fs/ext4/extents.c in the Linux kernel allowed local users to cause
   a denial of service (BUG and system crash) via a write operation on
   the last block of a large file, followed by a sync operation.

   CVE-2010-2803: The drm_ioctl function in drivers/gpu/drm/drm_drv.c
   in the Direct Rendering Manager (DRM) subsystem in the Linux kernel
   allowed local users to obtain potentially sensitive information from
   kernel memory by requesting a large memory-allocation amount.

   CVE-2010-2798: The gfs2_dirent_find_space function in fs/gfs2/dir.c
   in the Linux kernel used an incorrect size value in calculations
   associated with sentinel directory entries, which allowed local users   to cause a denial of service (NULL pointer dereference and panic) and
   possibly have unspecified other impact by renaming a file in a GFS2
   filesystem, related to the gfs2_rename function in fs/gfs2/ops_inode.c.

2) Solution or Work-Around

   There is no workaround, please install the fixed packages.

3) Special Instructions and Notes

   Please reboot the machine after 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.

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
                .
