[RHSA-2002:210-06] New kernel 2.2 packages fix local vulnerabilities
From: bugzilla () redhat com
Date: Thu, 17 Oct 2002 06:11 -0400

---------------------------------------------------------------------
                   Red Hat, Inc. Red Hat Security Advisory

Synopsis:          New kernel 2.2 packages fix local vulnerabilities
Advisory ID:       RHSA-2002:210-06
Issue date:        2002-09-23
Updated on:        2002-10-10
Product:           Red Hat Linux
Keywords:          elevated local root kernel
Cross references:  
Obsoletes:         RHSA-2001:142
---------------------------------------------------------------------

1. Topic:

Some potential local security vulnerabilities were found in the kernel
during code audits; these have been fixed in the 2.2.22 kernel.

2. Relevant releases/architectures:

Red Hat Linux 6.2 - alpha, i386, i586, i686, sparc, sparc64
Red Hat Linux 7.0 - alpha, i386, i586, i686

3. Problem description:

The Linux kernel handles the basic functions of the operating system. A
security code audit of the 2.2 kernel found a number of possible local
security vulnerabilities. These vulnerabilities could allow a local user
to obtain elevated (root) privileges.  

Red Hat Linux 6.2 and 7.0 shipped with the 2.2 kernel and are both
vulnerable to these issues.

All Red Hat Linux users using the 2.2 kernel should upgrade to the errata
pacakages contaning the 2.2.22 kernel which are not vulnerable to these issues.

Many thanks to Silvio Cesare and Solar Designer for their work in
discovering these issues.

4. Solution:

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

The procedure for upgrading the kernel is documented at:

http://www.redhat.com/support/docs/howto/kernel-upgrade/kernel-upgrade.html

Please read the directions for your architecture carefully before
proceeding with the kernel upgrade.

Please note that this update is also available via Red Hat Network.  Many
people find this to be an easier way to apply updates.  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. Note that you need to select the kernel
explicitly on default configurations of up2date.

5. RPMs required:
