    3. Description:
    
    The kernel packages contain the Linux kernel, the core of any Linux
    operating system.
    
    * It was found that Linux kernel's ptrace subsystem did not properly
    sanitize the address-space-control bits when the program-status word (PSW)
    was being set. On IBM S/390 systems, a local, unprivileged user could use
    this flaw to set address-space-control bits to the kernel space, and thus
    gain read and write access to kernel memory. (CVE-2014-3534, Important)
    
    * It was found that the permission checks performed by the Linux kernel
    when a netlink message was received were not sufficient. A local,
    unprivileged user could potentially bypass these restrictions by passing a
    netlink socket as stdout or stderr to a more privileged process and
    altering the output of this process. (CVE-2014-0181, Moderate)
    
    * It was found that a remote attacker could use a race condition flaw in
    the ath_tx_aggr_sleep() function to crash the system by creating large
    network traffic on the system's Atheros 9k wireless network adapter.
    (CVE-2014-2672, Moderate)
    
    * A flaw was found in the way the Linux kernel performed forking inside of
    a transaction. A local, unprivileged user on a PowerPC system that supports
    transactional memory could use this flaw to crash the system.
    (CVE-2014-2673, Moderate)
    
    * A race condition flaw was found in the way the Linux kernel's mac80211
    subsystem implementation handled synchronization between TX and STA wake-up
    code paths. A remote attacker could use this flaw to crash the system.
    (CVE-2014-2706, Moderate)
    
    * An integer underflow flaw was found in the way the Linux kernel's Stream
    Control Transmission Protocol (SCTP) implementation processed certain
    COOKIE_ECHO packets. By sending a specially crafted SCTP packet, a remote
    attacker could use this flaw to prevent legitimate connections to a
    particular SCTP server socket to be made. (CVE-2014-4667, Moderate)
    
    Red Hat would like to thank Martin Schwidefsky of IBM for reporting
    CVE-2014-3534, Andy Lutomirski for reporting CVE-2014-0181, and Gopal Reddy
    Kodudula of Nokia Siemens Networks for reporting CVE-2014-4667.
    
    This update also fixes the following bugs:
    
    * Due to a NULL pointer dereference bug in the IPIP and SIT tunneling code,
    a kernel panic could be triggered when using IPIP or SIT tunnels with
    IPsec. This update restructures the related code to avoid a NULL pointer
    dereference and the kernel no longer panics when using IPIP or SIT tunnels
    with IPsec. (BZ#1114957)
    
    * Previously, an IBM POWER8 system could terminate unexpectedly when the
    kernel received an IRQ while handling a transactional memory re-checkpoint
    critical section. This update ensures that IRQs are disabled in this
    situation and the problem no longer occurs. (BZ#1113150)
    
    * A missing read memory barrier, rmb(), in the bnx2x driver caused the
    kernel to crash under various circumstances. This problem has been fixed
    by adding an rmb() call to the relevant place in the bnx2x code.
    (BZ#1107721)
    
    * The hpwdt driver previously emitted a panic message that was misleading
    on certain HP systems. This update ensures that upon a kernel panic, hpwdt
    displays information valid on all HP systems. (BZ#1096961)
    
    * The qla2xxx driver has been upgraded to version 8.06.00.08.07.0-k3,
    which provides a number of bug fixes over the previous version in order to
    correct various timeout problems with the mailbox commands. (BZ#1112389)
    
    * The SCSI mid-layer could retry an I/O operation indefinitely if a storage
    array repeatedly returned a CHECK CONDITION status to that I/O operation
    but the sense data was invalid. This update fixes the problem by limiting
    a time for which is such an I/O operation retried. (BZ#1114468)
    
    All kernel users are advised to upgrade to these updated packages, which
    contain backported patches to correct these issues. The system must be
    rebooted for this update to take effect.
    
    4. Solution:
    
    Before applying this update, make sure all previously released errata
    relevant to your system have been applied.
    
    This update is available via the Red Hat Network. Details on how to use the
    Red Hat Network to apply this update are available at
    https://access.redhat.com/articles/11258
    
    To install kernel packages manually, use "rpm -ivh [package]". Do not use
    "rpm -Uvh" as that will remove the running kernel binaries from your
    system. You may use "rpm -e" to remove old kernels after determining that
    the new kernel functions properly on your system.
