Red Hat Security Advisory

Synopsis: Updated 2.4 kernel fixes vulnerability
Advisory ID: RHSA-2003:098-03
Issue date: 2003-03-17
Updated on: 2003-06-02
Product: Red Hat Linux
Keywords: ptrace
Cross references:  
Obsoletes: RHSA-2003:025-20 RHBA-2003:069-12
CVE Names: CAN-2003-0127

1. Topic:

Updated kernel packages for Red Hat Linux 7.1, 7.2, 7.3, and 8.0 are now available. These packages fix a ptrace-related vulnerability that can lead to elevated (root) privileges.

[Updated 30 March 2003]
Updated kernel packages for Red Hat Linux 7.2 ia64 have been added.

[Updated 28 May 2003]
Replacement kernel packages for Red Hat Linux 7.2 ia64 have been added; the previous packages did not contain the fix for the ptrace vulnerability.

2. Relevant releases/architectures:

Red Hat Linux 7.1 - athlon, i386, i586, i686
Red Hat Linux 7.2 - athlon, i386, i586, i686, ia64
Red Hat Linux 7.3 - athlon, i386, i586, i686
Red Hat Linux 8.0 - athlon, i386, i586, i686

3. Problem description:

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

A vulnerability has been found in version 2.4.18 of the kernel. This vulnerability makes it possible for local users to gain elevated (root) privileges without authorization. This advisory includes updates for Red Hat Linux 7.1, 7.2, 7.3, and 8.0.

All users of Red Hat Linux 7.1, 7.2, 7.3, and 8.0 should upgrade to these errata packages, which contain patches to fix the vulnerability.

4. Solution:

Before applying this update, make sure all previously released errata relevant to your system have been applied, especially the additional packages from RHSA-2002:205 and RHSA-2002:206.

The procedure for upgrading the kernel manually is documented at:

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

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.
