______________________________________________________________________________

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-2009-3939: A sysctl variable of the megaraid_sas driver was
   world writable, allowing local users to cause a denial of service or
   potential code execution.
   CVSS v2 Base Score: 6.6 (MEDIUM) (AV:L/AC:L/Au:N/C:N/I:C/A:C)


   CVE-2009-3889: The dbg_lvl file for the megaraid_sas driver in the
   Linux kernel before 2.6.27 has world-writable permissions, which
   allows local users to change the (1) behavior and (2) logging level
   of the driver by modifying this file.
   This was already fine in SLES 10 SP3 GA due to a driver update of the
   megaraid_sas driver and is just listed for completeness here.
   CVSS v2 Base Score: 4.6 (MEDIUM) (AV:L/AC:L/Au:N/C:P/I:P/A:P)


   CVE-2009-4005: The collect_rx_frame function in
   drivers/isdn/hisax/hfc_usb.c in the Linux kernel before 2.6.32-rc7
   allows attackers to have an unspecified impact via a crafted HDLC
   packet that arrives over ISDN and triggers a buffer under-read.
   This requires the attacker to be able to send ISDN low level frames 
   to the host.
   CVSS v2 Base Score: 7.2 (HIGH) (AV:L/AC:L/Au:N/C:C/I:C/A:C)


   CVE-2009-3080: A negative offset in a ioctl in the GDTH RAID driver
   was fixed.
   CVSS v2 Base Score: 7.2 (HIGH) (AV:L/AC:L/Au:N/C:C/I:C/A:C)


   CVE-2009-4021: The fuse_direct_io function in fs/fuse/file.c in the
   fuse subsystem in the Linux kernel might allow attackers to cause a
   denial of service (invalid pointer dereference and OOPS) via vectors
   possibly related to a memory-consumption attack.
   CVSS v2 Base Score: 4.9 (MEDIUM) (AV:L/AC:L/Au:N/C:N/I:N/A:C)


   CVE-2009-2903: Memory leak in the AppleTalk subsystem in the Linux
   kernel when the AppleTalk and ipddp modules are loaded but the ipddp"N"
   device is not found, allows remote attackers to cause a denial of
   service (memory consumption) via IP-DDP datagrams.
   CVSS v2 Base Score: 7.1 (AV:N/AC:M/Au:N/C:N/I:N/A:C)


   CVE-2009-3621: net/unix/af_unix.c in the Linux kernel allows local
   users to cause a denial of service (system hang) by creating an
   abstract-namespace AF_UNIX listening socket, performing a shutdown
   operation on this socket, and then performing a series of connect
   operations to this socket.
   CVSS v2 Base Score: 4.9 (MEDIUM) (AV:L/AC:L/Au:N/C:N/I:N/A:C)


   CVE-2009-3612 / CVE-2005-4881: The tcf_fill_node function in
   net/sched/cls_api.c in the netlink subsystem in the Linux kernel 2.6.x
   before 2.6.32-rc5, and 2.4.37.6 and earlier, does not initialize a
   certain tcm__pad2 structure member, which might allow local users
   to obtain sensitive information from kernel memory via unspecified
   vectors.  NOTE: this issue existed because of an incomplete fix for
   CVE-2005-4881.
   CVSS v2 Base Score: 4.9 (MEDIUM) (AV:L/AC:L/Au:N/C:C/I:N/A:N)


   CVE-2009-3620: The ATI Rage 128 (aka r128) driver in the Linux
   kernel does not properly verify Concurrent Command Engine (CCE)
   state initialization, which allows local users to cause a denial of
   service (NULL pointer dereference and system crash) or possibly gain
   privileges via unspecified ioctl calls.
   CVSS v2 Base Score: 4.9 (MEDIUM) (AV:L/AC:L/Au:N/C:N/I:N/A:C)


   CVE-2009-3726: The nfs4_proc_lock function in fs/nfs/nfs4proc.c
   in the NFSv4 client in the Linux kernel allows remote NFS servers
   to cause a denial of service (NULL pointer dereference and panic)
   by sending a certain response containing incorrect file attributes,
   which trigger attempted use of an open file that lacks NFSv4 state.
   CVSS v2 Base Score: 7.8 (HIGH) (AV:N/AC:L/Au:N/C:N/I:N/A:C)

   The rio and sx serial multi port card drivers were disabled via a
   modprobe blacklist due to severe bugs.

   For a full list of changes, please read 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 this 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
                .
