Red Hat Security Advisory

Synopsis: Important: kernel security update
Advisory ID: RHSA-2007:0085-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2007-0085.html
Issue date: 2007-02-27
Updated on: 2007-02-27
Product: Red Hat Enterprise Linux
Keywords: nahant kernel update
Obsoletes: RHSA-2007:0014
CVE Names: CVE-2007-0001 CVE-2007-0006
- ---------------------------------------------------------------------

1. Summary:

Updated kernel packages that fix two security issues and a bug in the Red Hat
Enterprise Linux 4 kernel are now available.

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 AS version 4 - i386, ia64, noarch, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, noarch, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, noarch, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, noarch, x86_64

3. Problem description:

The Linux kernel handles the basic functions of the operating system.

These new kernel packages contain fixes for two security issues:

* a flaw in the key serial number collision avoidance algorithm of the
keyctl subsystem that allowed a local user to cause a denial of service
(CVE-2007-0006, Important)

* a flaw in the file watch implementation of the audit subsystems that
allowed a local user to cause a denial of service (panic). To exploit this
flaw a privileged user must have previously created a watch for a file
(CVE-2007-0001, Moderate)

In addition to the security issues described above, a fix for the SCTP
subsystem to address a system crash which may be experienced in Telco
environments has been included.

Red Hat Enterprise Linux 4 users are advised to upgrade their kernels to
the packages associated with their machine architecture and configurations
as listed in this erratum.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via Red Hat Network. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

5. Bug IDs fixed (http://bugzilla.redhat.com/):

223129 - CVE-2007-0001 kernel panic watching /etc/passwd
223818 - kernel panic in sctp module
227495 - CVE-2007-0006 Key serial number collision problem
