"This update fixes the following security issues :

  - A flaw was found in the sctp_icmp_proto_unreachable()
    function in the Linux kernel's Stream Control
    Transmission Protocol (SCTP) implementation. A remote
    attacker could use this flaw to cause a denial of
    service. (CVE-2010-4526, Important)

  - A missing boundary check was found in the dvb_ca_ioctl()
    function in the Linux kernel's av7110 module. On systems
    that use old DVB cards that require the av7110 module, a
    local, unprivileged user could use this flaw to cause a
    denial of service or escalate their privileges.
    (CVE-2011-0521, Important)

  - A race condition was found in the way the Linux kernel's
    InfiniBand implementation set up new connections. This
    could allow a remote user to cause a denial of service.
    (CVE-2011-0695, Important)

  - A heap overflow flaw in the iowarrior_write() function
    could allow a user with access to an IO-Warrior USB
    device, that supports more than 8 bytes per report, to
    cause a denial of service or escalate their privileges.
    (CVE-2010-4656, Moderate)

  - A flaw was found in the way the Linux Ethernet bridge
    implementation handled certain IGMP (Internet Group
    Management Protocol) packets. A local, unprivileged user
    on a system that has a network interface in an Ethernet
    bridge could use this flaw to crash that system
    (CVE-2011-0716, Moderate)

  - A NULL pointer dereference flaw was found in the Generic
    Receive Offload (GRO) functionality in the Linux
    kernel's networking implementation. If both GRO and
    promiscuous mode were enabled on an interface in a
    virtual LAN (VLAN), it could result in a denial of
    service when a malformed VLAN frame is received on that
    interface. (CVE-2011-1478, Moderate)

  - A missing initialization flaw in the Linux kernel could
    lead to an information leak. (CVE-2010-3296, Low)

  - A missing security check in the Linux kernel's
    implementation of the install_special_mapping() function
    could allow a local, unprivileged user to bypass the
    mmap_min_addr protection mechanism. (CVE-2010-4346, Low)

  - A logic error in the orinoco_ioctl_set_auth() function
    in the Linux kernel's ORiNOCO wireless extensions
    support implementation could render TKIP countermeasures
    ineffective when it is enabled, as it enabled the card
    instead of shutting it down. (CVE-2010-4648, Low)

  - A missing initialization flaw was found in the
    ethtool_get_regs() function in the Linux kernel's
    ethtool IOCTL handler. A local user who has the
    CAP_NET_ADMIN capability could use this flaw to cause an
    information leak. (CVE-2010-4655, Low)

  - An information leak was found in the Linux kernel's
    task_show_regs() implementation. On IBM S/390 systems, a
    local, unprivileged user could use this flaw to read
    /proc/[PID]/status files, allowing them to discover the
    CPU register values of processes. (CVE-2011-0710, Low)

This update also fixes several bugs.

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

"From Red Hat Security Advisory 2011:0421 :

Updated kernel packages that fix multiple security issues and several
bugs are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

This update fixes the following security issues :

* A flaw was found in the sctp_icmp_proto_unreachable() function in
the Linux kernel's Stream Control Transmission Protocol (SCTP)
implementation. A remote attacker could use this flaw to cause a
denial of service. (CVE-2010-4526, Important)

the Linux kernel's av7110 module. On systems that use old DVB cards
that require the av7110 module, a local, unprivileged user could use
this flaw to cause a denial of service or escalate their privileges.
(CVE-2011-0521, Important)

* A race condition was found in the way the Linux kernel's InfiniBand
implementation set up new connections. This could allow a remote user
to cause a denial of service. (CVE-2011-0695, Important)

* A heap overflow flaw in the iowarrior_write() function could allow a

local, unprivileged user on a system that has a network interface in

implementation. If both GRO and promiscuous mode were enabled on an
interface in a virtual LAN (VLAN), it could result in a denial of
service when a malformed VLAN frame is received on that interface.

* A missing security check in the Linux kernel's implementation of the
install_special_mapping() function could allow a local, unprivileged
user to bypass the mmap_min_addr protection mechanism. (CVE-2010-4346,
Low)

render TKIP countermeasures ineffective when it is enabled, as it

Red Hat would like to thank Jens Kuehnel for reporting CVE-2011-0695;
Kees Cook for reporting CVE-2010-4656 and CVE-2010-4655; Dan Rosenberg
for reporting CVE-2010-3296; and Tavis Ormandy for reporting
CVE-2010-4346.

This update also fixes several bugs. Documentation for these bug fixes
will be available shortly from the Technical Notes document linked to
in the References section.

Users should upgrade to these updated packages, which contain
backported patches to correct these issues, and fix the bugs noted in
the Technical Notes. The system must be rebooted for this update to
