Red Hat Security Advisory

 

Synopsis: Important: kernel security update

Advisory ID: RHSA-2009:0021-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-0021.html

Issue date: 2009-02-24

CVE Names: CVE-2008-5029 CVE-2008-5079 CVE-2008-5182

CVE-2008-5300

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

 

1. Summary:

 

Updated kernel packages that resolve several security issues are now

available for Red Hat Enterprise Linux 5.2 Extended Update Support.

 

This update has been rated as having important security impact by the Red

Hat Security Response Team.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux (v. 5.2.z server) - i386, ia64, noarch, ppc, s390x, x86_64

 

3. Description:

 

The kernel packages contain the Linux kernel, the core of any Linux

operating system.

 

This update includes backported fixes for four security issues. These

issues only affected users of Red Hat Enterprise Linux 5.2 Extended Update

Support as they have already been addressed for users of Red Hat Enterprise

Linux 5 in the 5.3 update, RHSA-2009:0225.

 

In accordance with the support policy, future security updates to Red Hat

Enterprise Linux 5.2 Extended Update Support will only include issues of

critical security impact.

 

* when fput() was called to close a socket, the __scm_destroy() function

in the Linux kernel could make indirect recursive calls to itself. This

could, potentially, lead to a denial of service issue. (CVE-2008-5029,

Important)

 

* the sendmsg() function in the Linux kernel did not block during UNIX

socket garbage collection. This could, potentially, lead to a local denial

of service. (CVE-2008-5300, Important)

 

* a flaw was found in the Asynchronous Transfer Mode (ATM) subsystem. A

local, unprivileged user could use the flaw to listen on the same socket

more than once, possibly causing a denial of service. (CVE-2008-5079,

Important)

 

* a race condition was found in the Linux kernel "inotify" watch removal

and umount implementation. This could allow a local, unprivileged user

to cause a privilege escalation or a denial of service. (CVE-2008-5182,

Important)

 

Users should upgrade to these updated packages, which contain backported

patches to correct these issues. Note: for this update to take effect, the

system must be rebooted.

 

4. Solution:

 

Before applying this update, make sure that all previously-released

errata relevant to your system have been applied.

 

This update is available via Red Hat Network. Details on how to use

the Red Hat Network to apply this update are available at
