1) Problem Description and Brief Discussion

   The SUSE Linux Enterprise 11 and openSUSE 11.1 Kernel were updated to 2.6.27.45 fixing
   various bugs and security issues.

   CVE-2010-0622: The wake_futex_pi function in kernel/futex.c in the
   Linux kernel before 2.6.33-rc7 does not properly handle certain unlock
   operations for a Priority Inheritance (PI) futex, which allows local
   users to cause a denial of service (OOPS) and possibly have unspecified
   other impact via vectors involving modification of the futex value from
   user space.

   CVE-2010-0307: The load_elf_binary function in fs/binfmt_elf.c in the
   Linux kernel before 2.6.32.8 on the x86_64 platform does not ensure that
   the ELF interpreter is available before a call to the SET_PERSONALITY
   macro, which allows local users to cause a denial of service (system
   crash) via a 32-bit application that attempts to execute a 64-bit
   application and then triggers a segmentation fault, as demonstrated by
   amd64_killer, related to the flush_old_exec function.

   CVE-2010-0410: Users could send/allocate arbitrary amounts of
   NETLINK_CONNECTOR messages to the kernel, causing OOM condition, killing
   selected processes or halting the system.

   CVE-2010-0415: The do_pages_move function in mm/migrate.c in the Linux
   kernel before 2.6.33-rc7 does not validate node values, which allows
   local users to read arbitrary kernel memory locations, cause a denial of
   service (OOPS), and possibly have unspecified other impact by specifying
   a node that is not part of the kernels node set.

   CVE-2010-0007: net/bridge/netfilter/ebtables.c in the ebtables module in
   the netfilter framework in the Linux kernel before 2.6.33-rc4 does not
   require the CAP_NET_ADMIN capability for setting or modifying rules, which
   allows local users to bypass intended access restrictions and configure
   arbitrary network-traffic filtering via a modified ebtables application.

   CVE-2009-4536: drivers/net/e1000/e1000_main.c in the e1000 driver in the
   Linux kernel 2.6.32.3 and earlier 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-2009-4538: drivers/net/e1000e/netdev.c in the e1000e driver in the
   Linux kernel 2.6.32.3 and earlier does not properly check the size of
   an Ethernet frame that exceeds the MTU, which allows remote attackers
   to have an unspecified impact via crafted packets.
   It is not clear if this can be used for code execution.

   CVE-2010-0003: The print_fatal_signal function in kernel/signal.c
   in the Linux kernel before 2.6.32.4 on the i386 platform, when
   print-fatal-signals is enabled, allows local users to discover the
   contents of arbitrary memory locations by jumping to an address and
   then reading a log file, and might allow local users to cause a denial
   of service (system slowdown or crash) by jumping to an address.

   CVE-2009-3939: The poll_mode_io file for the megaraid_sas driver in the
   Linux kernel 2.6.31.6 and earlier has world-writable permissions, which
   allows local users to change the I/O mode of the driver by modifying
   this file.

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.

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
