This update fixes the following security issues :

  - An integer overflow flaw in ib_uverbs_poll_cq() could
    allow a local, unprivileged user to cause a denial of
    service or escalate their privileges. (CVE-2010-4649,
    Important)

  - A race condition in the way new InfiniBand connections
    were set up could allow a remote user to cause a denial
    of service. (CVE-2011-0695, Important)

  - A flaw in the Stream Control Transmission Protocol
    (SCTP) implementation could allow a remote attacker to
    cause a denial of service if the sysctl
    'net.sctp.addip_enable' variable was turned on (it is
    off by default). (CVE-2011-1573, Important)

  - Flaws in the AGPGART driver implementation when handling
    certain IOCTL commands could allow a local, unprivileged
    user to cause a denial of service or escalate their
    privileges. (CVE-2011-1745, CVE-2011-2022, Important)

  - An integer overflow flaw in agp_allocate_memory() could
    allow a local, unprivileged user to cause a denial of
    service or escalate their privileges. (CVE-2011-1746,
    Important)

  - A flaw allowed napi_reuse_skb() to be called on VLAN
    (virtual LAN) packets. An attacker on the local network
    could trigger this flaw by sending specially crafted
    packets to a target system, possibly causing a denial of
    service. (CVE-2011-1576, Moderate)

  - An integer signedness error in next_pidmap() could allow
    a local, unprivileged user to cause a denial of service.
    (CVE-2011-1593, Moderate)

  - A flaw in the way the Xen hypervisor implementation
    handled CPUID instruction emulation during virtual
    machine exits could allow an unprivileged guest user to
    crash a guest. This only affects systems that have an
    Intel x86 processor with the Intel VT-x extension
    enabled. (CVE-2011-1936, Moderate)

  - A flaw in inet_diag_bc_audit() could allow a local,
    unprivileged user to cause a denial of service (infinite
    loop). (CVE-2011-2213, Moderate)

  - A missing initialization flaw in the XFS file system
    implementation could lead to an information leak.
    (CVE-2011-0711, Low)

  - A flaw in ib_uverbs_poll_cq() could allow a local,
    unprivileged user to cause an information leak.
    (CVE-2011-1044, Low)

  - A missing validation check was found in the signals
    implementation. A local, unprivileged user could use
    this flaw to send signals via the sigqueueinfo system
    call, with the si_code set to SI_TKILL and with spoofed
    process and user IDs, to other processes. Note: This
    flaw does not allow existing permission checks to be
    bypassed; signals can only be sent if your privileges
    allow you to already do so. (CVE-2011-1182, Low)

  - A heap overflow flaw in the EFI GUID Partition Table
    (GPT) implementation could allow a local attacker to
    cause a denial of service by mounting a disk containing
    specially crafted partition tables. (CVE-2011-1776, Low)

  - Structure padding in two structures in the Bluetooth
    implementation was not initialized properly before being
    copied to user-space, possibly allowing local,
    unprivileged users to leak kernel stack memory to
    user-space. (CVE-2011-2492, Low)

This update fixes several bugs.

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