"This update fixes the following security issues :

  - Information leak flaws were found in the Linux kernel
    Traffic Control Unit implementation. A local attacker
    could use these flaws to cause the kernel to leak kernel
    memory to user-space, possibly leading to the disclosure
    of sensitive information. (CVE-2010-2942, Moderate)

  - A flaw was found in the tcf_act_police_dump() function
    in the Linux kernel network traffic policing
    implementation. A data structure in
    tcf_act_police_dump() was not initialized properly
    before being copied to user-space. A local, unprivileged
    user could use this flaw to cause an information leak.
    (CVE-2010-3477, Moderate)

  - A missing upper bound integer check was found in the
    sys_io_submit() function in the Linux kernel
    asynchronous I/O implementation. A local, unprivileged
    user could use this flaw to cause an information leak.
    (CVE-2010-3067, Low)

This update also fixes the following bugs :

  - When two systems using bonding devices in the adaptive
    load balancing (ALB) mode communicated with each other,
    an endless loop of ARP replies started between these two
    systems due to a faulty MAC address update. With this
    update, the MAC address update no longer creates
    unneeded ARP replies. (BZ#629239)

  - When running the Connectathon NFS Testsuite with certain
    clients and Scientific Linux 4.8 as the server,
    nfsvers4, lock, and test2 failed the Connectathon test.
    (BZ#625535)

  - For UDP/UNIX domain sockets, due to insufficient memory
    barriers in the network code, a process sleeping in
    select() may have missed notifications about new data.
    In rare cases, this bug may have caused a process to
    sleep forever. (BZ#640117)

  - In certain situations, a bug found in either the HTB or
    TBF network packet schedulers in the Linux kernel could
    have caused a kernel panic when using Broadcom network
    cards with the bnx2 driver. (BZ#624363)

  - Previously, allocating fallback cqr for DASD
    reserve/release IOCTLs failed because it used the memory
    pool of the respective device. This update preallocates
    sufficient memory for a single reserve/release request.
    (BZ#626828)

  - In some situations a bug prevented 'force online'
    succeeding for a DASD device. (BZ#626827)

  - Using the 'fsstress' utility may have caused a kernel
    panic. (BZ#633968)

  - This update introduces additional stack guard patches.
    (BZ#632515)

  - A bug was found in the way the megaraid_sas driver
    handled physical disks and management IOCTLs. All
    physical disks were exported to the disk layer, allowing
    an oops in megasas_complete_cmd_dpc() when completing
    the IOCTL command if a timeout occurred. (BZ#631903)

  - Previously, a warning message was returned when a large
    amount of messages was passed through netconsole and a
    considerable amount of network load was added. With this
    update, the warning message is no longer displayed.
    (BZ#637729)

  - Executing a large 'dd' command (1 to 5GB) on an iSCSI
    device with the qla3xxx driver caused a system crash due
    to the incorrect storing of a private data structure.
    With this update, the size of the stored data structure
    is checked and the system crashes no longer occur.
    (BZ#624364)

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