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

The following security issues were fixed :

  - A crafted NFS write request might have caused a buffer
    overwrite, potentially causing a kernel crash.
    (CVE-2010-2521)

  - The x86_64 copy_to_user implementation might have leaked
    kernel memory depending on specific user buffer setups.
    (CVE-2008-0598)

  - drivers/net/r8169.c in the r8169 driver in the Linux
    kernel did not properly check the size of an Ethernet
    frame that exceeds the MTU, which allows remote
    attackers to (1) cause a denial of service (temporary
    network outage) via a packet with a crafted size, in
    conjunction with certain packets containing A characters
    and certain packets containing E characters; or (2)
    cause a denial of service (system crash) via a packet
    with a crafted size, in conjunction with certain packets
    containing '\0' characters, related to the value of the
    status register and erroneous behavior associated with
    the RxMaxSize register. NOTE: this vulnerability exists
    because of an incorrect fix for CVE-2009-1389.
    (CVE-2009-4537)

  - Use-after-free vulnerability in net/ipv4/tcp_input.c in
    the Linux kernel 2.6 when IPV6_RECVPKTINFO is set on a
    listening socket, allowed remote attackers to cause a
    denial of service (kernel panic) via a SYN packet while
    the socket is in a listening (TCP_LISTEN) state, which
    is not properly handled causes the skb structure to be
    freed. (CVE-2010-1188)

  - The (1) real_lookup and (2) __lookup_hash functions in
    fs/namei.c in the vfs implementation in the Linux kernel
    did not prevent creation of a child dentry for a deleted
    (aka S_DEAD) directory, which allowed local users to
    cause a denial of service ('overflow' of the UBIFS
    orphan area) via a series of attempted file creations
    within deleted directories. (CVE-2008-3275)

  - The nfs_lock function in fs/nfs/file.c in the Linux
    kernel did not properly remove POSIX locks on files that
    are setgid without group-execute permission, which
    allows local users to cause a denial of service (BUG and
    system crash) by locking a file on an NFS filesystem and
    then changing this files permissions, a related issue to
    CVE-2010-0727. (CVE-2007-6733)

  - The do_coredump function in fs/exec.c in Linux kernel
    did not change the UID of a core dump file if it exists
    before a root process creates a core dump in the same
    location, which might have allowed local users to obtain
    sensitive information. (CVE-2007-6206)

  - fs/namei.c in the Linux kernel did not always follow NFS
    automount 'symlinks,' which allowed attackers to have an
    unknown impact, related to LOOKUP_FOLLOW.
    (CVE-2010-1088)

  - Stack-based buffer overflow in the hfs subsystem in the
    Linux kernel allowed remote attackers to have an
    unspecified impact via a crafted Hierarchical File
    System (HFS) filesystem, related to the hfs_readdir
    function in fs/hfs/dir.c. (CVE-2009-4020)

  - The processcompl_compat function in
    drivers/usb/core/devio.c in Linux kernel did not clear
    the transfer buffer before returning to userspace when a
    USB command fails, which might have made it easier for
    physically proximate attackers to obtain sensitive
    information (kernel memory). (CVE-2010-1083)"
