1) Problem Description and Brief Discussion

   This update fixes various security issues and some bugs in the SUSE
   Linux Enterprise 9 kernel.

   CVE-2009-4005: The collect_rx_frame function in
   drivers/isdn/hisax/hfc_usb.c in the Linux kernel allows attackers   to have an unspecified impact via a crafted HDLC packet that arrives
   over ISDN and triggers a buffer under-read.

   CVE-2009-3080: Array index error in the gdth_read_event function in
   drivers/scsi/gdth.c in the Linux kernel allows local users to cause
   a denial of service or possibly gain privileges via a negative event
   index in an IOCTL request.

   CVE-2010-0007: Missing CAP_NET_ADMIN checks in the ebtables netfilter
   code might have allowed local attackers to modify bridge firewall
   settings.

   CVE-2009-4536: drivers/net/e1000/e1000_main.c in the e1000 driver
   in the Linux kernel handles Ethernet frames that exceed the MTU by
   processing certain trailing payload data as if it were a complete
   frame, which allows remote attackers to bypass packet filters via a
   large packet with a crafted payload.

   CVE-2009-3889: The dbg_lvl file for the megaraid_sas driver in the
   Linux kernel has world-writable permissions, which allows local users   to change the (1) behavior and (2) logging level of the driver by
   modifying this file.

   CVE-2009-1883: The z90crypt_unlocked_ioctl function in the z90crypt
   driver in the Linux kernel does not perform a capability check for
   the Z90QUIESCE operation, which allows local users to leverage euid
   0 privileges to force a driver outage.

   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.

   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.

   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.

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.
