Red Hat Security Advisory

 

Synopsis: Moderate: kernel security, bug fix, and enhancement update

Advisory ID: RHSA-2011:0283-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-0283.html

Issue date: 2011-02-22

CVE Names: CVE-2010-4165 CVE-2010-4169 CVE-2010-4243

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

 

1. Summary:

 

Updated kernel packages that fix three security issues, several bugs, and

add two enhancements are now available for Red Hat Enterprise Linux 6.

 

The Red Hat Security Response Team has rated this update as having moderate

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 Desktop (v. 6) - i386, noarch, x86_64

Red Hat Enterprise Linux HPC Node (v. 6) - noarch, x86_64

Red Hat Enterprise Linux Server (v. 6) - i386, noarch, ppc64, s390x, x86_64

Red Hat Enterprise Linux Workstation (v. 6) - 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 divide-by-zero flaw was found in the tcp_select_initial_window()

function in the Linux kernel's TCP/IP protocol suite implementation. A

local, unprivileged user could use this flaw to trigger a denial of service

by calling setsockopt() with certain options. (CVE-2010-4165, Moderate)

 

* A use-after-free flaw in the mprotect() system call in the Linux kernel

could allow a local, unprivileged user to cause a local denial of service.

(CVE-2010-4169, Moderate)

 

* A flaw was found in the Linux kernel execve() system call implementation.

A local, unprivileged user could cause large amounts of memory to be

allocated but not visible to the OOM (Out of Memory) killer, triggering a

denial of service. (CVE-2010-4243, Moderate)

 

Red Hat would like to thank Steve Chen for reporting CVE-2010-4165, and

Brad Spengler for reporting CVE-2010-4243.

 

This update also fixes several bugs and adds two enhancements.

Documentation for these bug fixes and enhancements 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 and add the enhancements

noted in the Technical Notes. 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

https://access.redhat.com/kb/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.
