Red Hat Security Advisory

 

Synopsis: Important: kernel security update

Advisory ID: RHSA-2010:0677-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0677.html

Issue date: 2010-09-07

CVE Names: CVE-2010-2240

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

 

1. Summary:

 

Updated kernel packages that fix one security issue are now available for

Red Hat Enterprise Linux 4.7 Extended Update Support.

 

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.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux AS version 4.7.z - i386, ia64, noarch, ppc, s390, s390x, x86_64

Red Hat Enterprise Linux ES version 4.7.z - i386, ia64, 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 issue:

 

* When an application has a stack overflow, the stack could silently

overwrite another memory mapped area instead of a segmentation fault

occurring, which could cause an application to execute arbitrary code,

possibly leading to privilege escalation. It is known that the X Window

System server can be used to trigger this flaw. (CVE-2010-2240, Important)

 

Red Hat would like to thank the X.Org security team for reporting this

issue. Upstream acknowledges Rafal Wojtczuk as the original reporter.

 

Users should upgrade to these updated packages, which contain backported

patches to correct this issue. 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.

 

5. Bugs fixed (http://bugzilla.redhat.com/):

 

606611 - CVE-2010-2240 kernel: mm: keep a guard page below a grow-down stack segment
