"This update addresses the following security issues :

  - the sendmsg() function in the Linux kernel did not block
    during UNIX socket garbage collection. This could,
    potentially, lead to a local denial of service.
    (CVE-2008-5300, Important)

  - when fput() was called to close a socket, the
    __scm_destroy() function in the Linux kernel could make
    indirect recursive calls to itself. This could,
    potentially, lead to a local denial of service.
    (CVE-2008-5029, Important)

  - a deficiency was found in the Linux kernel virtual file
    system (VFS) implementation. This could allow a local,
    unprivileged user to make a series of file creations
    within deleted directories, possibly causing a denial of
    service. (CVE-2008-3275, Moderate)

  - a buffer underflow flaw was found in the Linux kernel
    IB700 SBC watchdog timer driver. This deficiency could
    lead to a possible information leak. By default, the
    '/dev/watchdog' device is accessible only to the root
    user. (CVE-2008-5702, Low)

  - the hfs and hfsplus file systems code failed to properly
    handle corrupted data structures. This could,
    potentially, lead to a local denial of service.
    (CVE-2008-4933, CVE-2008-5025, Low)

  - a flaw was found in the hfsplus file system
    implementation. This could, potentially, lead to a local
    denial of service when write operations were performed.
    (CVE-2008-4934, Low)

This update also fixes the following bugs :

  - when running Red Hat Enterprise Linux 4.6 and 4.7 on
    some systems running Intel® CPUs, the cpuspeed
    daemon did not run, preventing the CPU speed from being
    changed, such as not being reduced to an idle state when
    not in use.

  - mmap() could be used to gain access to beyond the first
    megabyte of RAM, due to insufficient checks in the Linux
    kernel code. Checks have been added to prevent this.

  - attempting to turn keyboard LEDs on and off rapidly on
    keyboards with slow keyboard controllers, may have
    caused key presses to fail.

  - after migrating a hypervisor guest, the MAC address
    table was not updated, causing packet loss and
    preventing network connections to the guest. Now, a
    gratuitous ARP request is sent after migration. This
    refreshes the ARP caches, minimizing network downtime.

  - writing crash dumps with diskdump may have caused a
    kernel panic on Non-Uniform Memory Access (NUMA) systems
    with certain memory configurations.

  - on big-endian systems, such as PowerPC, the getsockopt()
    function incorrectly returned 0 depending on the
    parameters passed to it when the time to live (TTL)
    value equaled 255, possibly causing memory corruption
    and application crashes.

  - a problem in the kernel packages provided by the
    RHSA-2008:0508 advisory caused the Linux kernel's
    built-in memory copy procedure to return the wrong error
    code after recovering from a page fault on AMD64 and
    Intel 64 systems. This may have caused other Linux
    kernel functions to return wrong error codes.

  - a divide-by-zero bug in the Linux kernel process
    scheduler, which may have caused kernel panics on
    certain systems, has been resolved.

  - the netconsole kernel module caused the Linux kernel to
    hang when slave interfaces of bonded network interfaces
    were started, resulting in a system hang or kernel panic
    when restarting the network.

  - the '/proc/xen/' directory existed even if systems were
    not running Red Hat Virtualization. This may have caused
    problems for third-party software that checks
    virtualization-ability based on the existence of
    '/proc/xen/'. Note: this update will remove the
    '/proc/xen/' directory on systems not running Red Hat
    Virtualization.

This updated kernel-utils package adds an enhancement in the way of
proper support for user-space frequency-scaling on multi-core systems."
