Synopsis: Important: kernel security and bug fix update

Advisory ID: RHSA-2010:0398-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0398.html

Issue date: 2010-05-06

CVE Names: CVE-2010-0307 CVE-2010-0410 CVE-2010-0730

CVE-2010-1085 CVE-2010-1086

=====================================================================

 

1. Summary:

 

Updated kernel packages that fix multiple security issues and several bugs

are now available for Red Hat Enterprise Linux 5.

 

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.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, noarch, ppc, s390x, x86_64

Red Hat Enterprise Linux Desktop (v. 5 client) - i386, noarch, x86_64

 

3. Description:

 

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 Unidirectional Lightweight Encapsulation (ULE)

implementation. A remote attacker could send a specially-crafted ISO

MPEG-2 Transport Stream (TS) frame to a target system, resulting in an

infinite loop (denial of service). (CVE-2010-1086, Important)

 

* on AMD64 systems, it was discovered that the kernel did not ensure the

ELF interpreter was available before making a call to the SET_PERSONALITY

macro. A local attacker could use this flaw to cause a denial of service by

running a 32-bit application that attempts to execute a 64-bit application.

(CVE-2010-0307, Moderate)

 

* a flaw was found in the kernel connector implementation. A local,

unprivileged user could trigger this flaw by sending an arbitrary number

of notification requests using specially-crafted netlink messages,

resulting in a denial of service. (CVE-2010-0410, Moderate)

 

* a flaw was found in the Memory-mapped I/O (MMIO) instruction decoder in

the Xen hypervisor implementation. An unprivileged guest user could use

this flaw to trick the hypervisor into emulating a certain instruction,

which could crash the guest (denial of service). (CVE-2010-0730, Moderate)

 

* a divide-by-zero flaw was found in the azx_position_ok() function in the

driver for Intel High Definition Audio, snd-hda-intel. A local,

unprivileged user could trigger this flaw to cause a kernel crash (denial

of service). (CVE-2010-1085, Moderate)

 

This update also fixes the following bugs:

 

* in some cases, booting a system with the "iommu=on" kernel parameter

resulted in a Xen hypervisor panic. (BZ#580199)

 

* the fnic driver flushed the Rx queue instead of the Tx queue after

fabric login. This caused crashes in some cases. (BZ#580829)

 

* "kernel unaligned access" warnings were logged to the dmesg log on some

systems. (BZ#580832)

 

* the "Northbridge Error, node 1, core: -1 K8 ECC error" error occurred on

some systems using the amd64_edac driver. (BZ#580836)

 

* in rare circumstances, when using kdump and booting a kernel with

"crashkernel=128M ( -at -) 16M", the kdump kernel did not boot after a crash.

(BZ#580838)

 

* TLB page table entry flushing was done incorrectly on IBM System z,

possibly causing crashes, subtle data inconsistency, or other issues.

(BZ#580839)

 

* iSCSI failover times were slower than in Red Hat Enterprise Linux 5.3.

(BZ#580840)

 

* fixed floating point state corruption after signal. (BZ#580841)

 

* in certain circumstances, under heavy load, certain network interface

cards using the bnx2 driver and configured to use MSI-X, could stop

processing interrupts and then network connectivity would cease.

(BZ#587799)

 

* cnic parts resets could cause a deadlock when the bnx2 device was

enslaved in a bonding device and that device had an associated VLAN.

(BZ#581148)

 

* some BIOS implementations initialized interrupt remapping hardware in a

way the Xen hypervisor implementation did not expect. This could have

caused a system hang during boot. (BZ#581150)

 

* AMD Magny-Cours systems panicked when booting a 32-bit kernel.

(BZ#580846)

 

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.

 

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

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.
