"Security fixes :

  - a NULL pointer dereference flaw was found in the Linux
    kernel NFSv4 implementation. Several of the NFSv4 file
    locking functions failed to check whether a file had
    been opened on the server before performing locking
    operations on it. A local, unprivileged user on a system
    with an NFSv4 share mounted could possibly use this flaw
    to cause a kernel panic (denial of service) or escalate
    their privileges. (CVE-2009-3726, Important)

  - a flaw was found in the sctp_process_unk_param()
    function in the Linux kernel Stream Control Transmission
    Protocol (SCTP) implementation. A remote attacker could
    send a specially crafted SCTP packet to an SCTP
    listening port on a target system, causing a kernel
    panic (denial of service). (CVE-2010-1173, Important)

  - a race condition between finding a keyring by name and
    destroying a freed keyring was found in the Linux kernel
    key management facility. A local, unprivileged user
    could use this flaw to cause a kernel panic (denial of
    service) or escalate their privileges. (CVE-2010-1437,
    Important)

Red Hat would like to thank Simon Vallet for responsibly reporting
CVE-2009-3726; and Jukka Taimisto and Olli Jarva of Codenomicon Ltd,
Nokia Siemens Networks, and Wind River on behalf of their customer,
for responsibly reporting CVE-2010-1173.

Bug fixes :

  - RHBA-2007:0791 introduced a regression in the Journaling
    Block Device (JBD). Under certain circumstances,
    removing a large file (such as 300 MB or more) did not
    result in inactive memory being freed, leading to the
    system having a large amount of inactive memory. Now,
    the memory is correctly freed. (BZ#589155)

  - the timer_interrupt() routine did not scale lost real
    ticks to logical ticks correctly, possibly causing time
    drift for 64-bit Scientific Linux 4 KVM (Kernel-based
    Virtual Machine) guests that were booted with the
    'divider=x' kernel parameter set to a value greater than
    1. 'warning: many lost ticks' messages may have been
    logged on the affected guest systems. (BZ#590551)

  - a bug could have prevented NFSv3 clients from having the
    most up-to-date file attributes for files on a given
    NFSv3 file system. In cases where a file type changed,
    such as if a file was removed and replaced with a
    directory of the same name, the NFSv3 client may not
    have noticed this change until stat(2) was called (for
    example, by running 'ls -l'). (BZ#596372)

  - RHBA-2007:0791 introduced bugs in the Linux kernel PCI-X
    subsystem. These could have caused a system deadlock on
    some systems where the BIOS set the default Maximum
    Memory Read Byte Count (MMRBC) to 4096, and that also
    use the Intel PRO/1000 Linux driver, e1000. Errors such
    as 'e1000: eth[x]: e1000_clean_tx_irq: Detected Tx Unit
    Hang' were logged. (BZ#596374)

  - an out of memory condition in a KVM guest, using the
    virtio-net network driver and also under heavy network
    stress, could have resulted in that guest being unable
    to receive network traffic. Users had to manually remove
    and re-add the virtio_net module and restart the network
    service before networking worked as expected. Such
    memory conditions no longer prevent KVM guests receiving
    network traffic. (BZ#597310)

  - when an SFQ qdisc that limited the queue size to two
    packets was added to a network interface, sending
    traffic through that interface resulted in a kernel
    crash. Such a qdisc no longer results in a kernel crash.
    (BZ#597312)

  - when an NFS client opened a file with the O_TRUNC flag
    set, it received a valid stateid, but did not use that
    stateid to perform the SETATTR call. Such cases were
    rejected by Red Hat Enterprise Linux 4 NFS servers with
    an 'NFS4ERR_BAD_STATEID' error, possibly preventing some
    NFS clients from writing files to an NFS file system.
    (BZ#597314)

The system must be rebooted for this update to take effect."
