"This update fixes the following security issues :

  - Missing sanity checks in the Intel i915 driver in the
    Linux kernel could allow a local, unprivileged user to
    escalate their privileges. (CVE-2010-2962, Important)

  - compat_alloc_user_space() in the Linux kernel 32/64-bit
    compatibility layer implementation was missing sanity
    checks. This function could be abused in other areas of
    the Linux kernel if its length argument can be
    controlled from user-space. On 64-bit systems, a local,
    unprivileged user could use this flaw to escalate their
    privileges. (CVE-2010-3081, Important)

  - A buffer overflow flaw in niu_get_ethtool_tcam_all() in
    the niu Ethernet driver in the Linux kernel, could allow
    a local user to cause a denial of service or escalate
    their privileges. (CVE-2010-3084, Important)

  - A flaw in the IA32 system call emulation provided in
    64-bit Linux kernels could allow a local user to
    escalate their privileges. (CVE-2010-3301, Important)

  - A flaw in sctp_packet_config() in the Linux kernel's
    Stream Control Transmission Protocol (SCTP)
    implementation could allow a remote attacker to cause a
    denial of service. (CVE-2010-3432, Important)

  - A missing integer overflow check in snd_ctl_new() in the
    Linux kernel's sound subsystem could allow a local,
    unprivileged user on a 32-bit system to cause a denial
    of service or escalate their privileges. (CVE-2010-3442,
    Important)

  - A flaw was found in sctp_auth_asoc_get_hmac() in the
    Linux kernel's SCTP implementation. When iterating
    through the hmac_ids array, it did not reset the last id
    element if it was out of range. This could allow a
    remote attacker to cause a denial of service.
    (CVE-2010-3705, Important)

  - A function in the Linux kernel's Reliable Datagram
    Sockets (RDS) protocol implementation was missing sanity
    checks, which could allow a local, unprivileged user to
    escalate their privileges. (CVE-2010-3904, Important)

  - A flaw in drm_ioctl() in the Linux kernel's Direct
    Rendering Manager (DRM) implementation could allow a
    local, unprivileged user to cause an information leak.
    (CVE-2010-2803, Moderate)

  - It was found that wireless drivers might not always
    clear allocated buffers when handling a driver-specific
    IOCTL information request. A local user could trigger
    this flaw to cause an information leak. (CVE-2010-2955,
    Moderate)

  - A NULL pointer dereference flaw in ftrace_regex_lseek()
    in the Linux kernel's ftrace implementation could allow
    a local, unprivileged user to cause a denial of service.
    Note: The debugfs file system must be mounted locally to
    exploit this issue. It is not mounted by default.
    (CVE-2010-3079, Moderate)

  - A flaw in the Linux kernel's packet writing driver could
    be triggered via the PKT_CTRL_CMD_STATUS IOCTL request,
    possibly allowing a local, unprivileged user with access
    to '/dev/pktcdvd/control' to cause an information leak.
    Note: By default, only users in the cdrom group have
    access to '/dev/pktcdvd/control'. (CVE-2010-3437,
    Moderate)

  - A flaw was found in the way KVM (Kernel-based Virtual
    Machine) handled the reloading of fs and gs segment
    registers when they had invalid selectors. A privileged
    host user with access to '/dev/kvm' could use this flaw
    to crash the host. (CVE-2010-3698, Moderate)

This update also fixes several bugs.

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

"Updated kernel packages that fix one security issue are now available
for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System
(CVSS) base score, which gives a detailed severity rating, is
available from the CVE link in the References section.

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

This update fixes the following security issue :

* The compat_alloc_user_space() function in the Linux kernel 32/64-bit
compatibility layer implementation was missing sanity checks. This
function could be abused in other areas of the Linux kernel if its
length argument can be controlled from user-space. On 64-bit systems,
a local, unprivileged user could use this flaw to escalate their
privileges. (CVE-2010-3081, Important)

Red Hat would like to thank Ben Hawkes for reporting this issue.

Red Hat is aware that a public exploit for this issue is available.
Refer to Knowledgebase article DOC-40265 for further details:
https://access.redhat.com/kb/docs/DOC-40265

Users should upgrade to these updated packages, which contain a
backported patch to correct this issue. The system must be rebooted
for this update to take effect."
