RHSA-2010:0958 - Security Advisory

  • Overview

Synopsis

Important: kernel-rt security and bug fix update

Type/Severity

Security Advisory: Important

Topic

Updated kernel-rt packages that fix multiple security issues and three bugs
are now available for Red Hat Enterprise MRG 1.3.

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.

Description

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

Security fixes:

  • 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)

  • 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 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)

  • Missing sanity checks in setup_arg_pages() in the Linux kernel. When

making the size of the argument and environment area on the stack very
large, it could trigger a BUG_ON(), resulting in a local denial of service.
(CVE-2010-3858, Moderate)

  • A flaw in ethtool_get_rxnfc() in the Linux kernel's ethtool IOCTL

handler. When it is called with a large info.rule_cnt, it could allow a
local user to cause an information leak. (CVE-2010-3861, Moderate)

  • A flaw in bcm_connect() in the Linux kernel's Controller Area Network

(CAN) Broadcast Manager. On 64-bit systems, writing the socket address may
overflow the procname character array. (CVE-2010-3874, Moderate)

  • A flaw in inet_csk_diag_dump() in the Linux kernel's module for

monitoring the sockets of INET transport protocols. By sending a netlink
message with certain bytecode, a local, unprivileged user could cause a
denial of service. (CVE-2010-3880, Moderate)

  • Missing sanity checks in gdth_ioctl_alloc() in the gdth driver in the

Linux kernel, could allow a local user with access to "/dev/gdth" on a
64-bit system to cause a denial of service or escalate their privileges.
(CVE-2010-4157, Moderate)

  • A use-after-free flaw in the mprotect() system call could allow a local,

unprivileged user to cause a local denial of service. (CVE-2010-4169,
Moderate)

  • Missing initialization flaws in the Linux kernel could lead to

information leaks. (CVE-2010-3876, CVE-2010-4072, CVE-2010-4073,
CVE-2010-4074, CVE-2010-4075, CVE-2010-4077, CVE-2010-4079, CVE-2010-4080,
CVE-2010-4082, CVE-2010-4083, CVE-2010-4158, Low)

Red Hat would like to thank Kees Cook for reporting CVE-2010-2962,
CVE-2010-3861, and CVE-2010-4072; Dan Rosenberg for reporting
CVE-2010-3442, CVE-2010-3705, CVE-2010-3874, CVE-2010-4073, CVE-2010-4074,
CVE-2010-4075, CVE-2010-4077, CVE-2010-4079, CVE-2010-4080, CVE-2010-4082,
CVE-2010-4083, and CVE-2010-4158; Brad Spengler for reporting
CVE-2010-3858; Nelson Elhage for reporting CVE-2010-3880; and Vasiliy
Kulikov for reporting CVE-2010-3876.

Bug fixes:

  • A vulnerability in the 32-bit compatibility code for the VIDIOCSMICROCODE

IOCTL in the Video4Linux implementation. It does not affect Red Hat
Enterprise MRG, but as a preventive measure, this update removes the code.
Red Hat would like to thank Kees Cook for reporting this vulnerability.
(BZ#642469)

  • The kernel-rt spec file was missing the crypto, drm, generated, and trace

header directories when generating the kernel-rt-devel package, resulting
in out-of-tree modules failing to build. (BZ#608784)

  • On computers without a supported Performance Monitoring Unit, a crash

would occur when running the "perf top" command, and occasionally other
perf commands. perf software events are now marked as IRQ safe to avoid
this crash. (BZ#647434)

Users should upgrade to these updated packages, which contain backported
patches to correct these issues. The system must be rebooted for this
update to take effect.

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
http://kbase.redhat.com/faq/docs/DOC-11259

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.
