Red Hat Security Advisory
Synopsis: Updated 2.4 kernel fixes vulnerabilities and driver bugs
Advisory ID: RHSA-2003:187-01
Issue date: 2003-05-22
Updated on: 2003-06-03
Product: Red Hat Linux
Keywords: DoS

---------------------------------------------------------------------
1. Topic:
Updated kernel packages are now available that contain fixes for security
vulnerabilities as well as fixes for bugs in the audigy, cmd640 IDE, and USB
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
Red Hat Linux 9 - athlon, i386, i586, i686
3. Problem description:
The Linux kernel handles the basic functions of the operating system.
Several security issues have been found that affect the Linux kernel:
Al Viro found a security issue in the tty layer whereby any user could
cause a kernel oops. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2002-0247 to this issue.
Andrea Arcangeli found an issue in the low-level mxcsr code in which a
malformed address would leave garbage in cpu state registers. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2003-0248 to this issue.
The TCP/IP fragment reassembly handling allows remote attackers to cause
a denial of service (CPU consumption) via packets that cause a large number
of hash table collisions, a vulnerability similar to CAN-2003-0244. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CAN-2003-0364 to this issue.
It is recommended that users upgrade to these erratum kernels, which
contain patches to correct these vulnerabilities. In addition, these
kernels fix a number of bugs:
Driver bugs fixes are included for the Silicon Image IDE driver, the USB
ohci driver, the Audigy driver, and the driver for the Olympus Camedia
digital camera.
A fix written by Andrew Morton is included to address a system stall caused
by file I/O in rare cases.
An updated fix corrects some bugs in the ptrace security fix for Red Hat
Linux 7.1, 7.2, 7.3, and 8.0. Note that these bugs were functionality
limitations, not additional security vulnerabilities.
Updated fixes for the ioperm security issue are also included.
A potential data corruption scenario has been identified. This
scenario can occur under heavy, complex I/O loads. The scenario
only occurs while performing memory mapped file I/O, where the
file is simultaneously unlinked and the corresponding file blocks
reallocated. Furthermore, the memory mapped writes must be to a
partial page at the end of a file on an ext3 file system. As such,
Red Hat considers this an unlikely scenario.
Red Hat Linux kernel erratum RHSA-2003:172 exposed a bug in the quota
packages for Red Hat Linux 7.1, 7.2 and 7.3; a fixed quota package is also
included in this erratum.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
To use Red Hat Network to upgrade the kernel, 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 if you are using the default configuration of up2date.
To install kernel packages manually, use "rpm -ivh <package>" and
modify system settings to boot the kernel you have installed. To
do this, edit /boot/grub/grub.conf and change the default entry to
"default=0" (or, if you have chosen to use LILO as your boot loader,
edit /etc/lilo.conf and run lilo)
Do not use "rpm -Uvh" as that will remove your running kernel binaries
from your system. You may use "rpm -e" to remove old kernels after
determining that the new kernel functions properly on your system.
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
