Subject: [RHSA-2002:262-07] New kernel fixes local denial of service issue

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

Synopsis:          New kernel fixes local denial of service issue
Advisory ID:       RHSA-2002:262-07
Issue date:        2002-09-23
Updated on:        2002-11-16
Product:           Red Hat Linux
Keywords:          bugtraq DoS

Obsoletes:         RHSA-2002:205 RHSA-2002:206
---------------------------------------------------------------------

1. Topic:

The kernel in Red Hat Linux 7.1, 7.1K, 7.2, 7.3, and 8.0 are vulnerable to
a local denial of service attack.  Updated packages are available which
address this vulnerability, as well as bugs in several drivers.

2. Relevant releases/architectures:

Red Hat Linux 7.1 - athlon, i386, i586, i686
Red Hat Linux 7.2 - athlon, i386, i586, i686
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 in the Linux kernel has been discovered in which a non-root
user can cause the machine to freeze. This kernel addresses the
vulnerability.  

Note: This bug is specific to the x86 architecture kernels only, and does
not affect ia64 or other architectures.

In addition, a bug in the maestro3 soundcard driver has been fixed as well
as a bug in the xircom pcmcia driver network driver and the tg3 network
driver for Broadcom gigabit ethernet chips.

All users of Red Hat Linux 7.1, 7.1K, 7.2, 7.3, and 8.0 should upgrade to
these errata packages, which are not vulnerable to this issue.

Thanks go to Christopher Devine for reporting the vulnerability on bugtraq,
and Petr Vandrovec for being the first to supply a fix to the community.

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 respectively.

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.
