Synopsis: Updated kernel packages resolve minor security vulnerabilities Advisory ID: RHSA-2004:044-01 Issue date: 2004-02-03 Updated on: 2004-02-03 Product: Red Hat Enterprise Linux Keywords: Cross references: Obsoletes: RHSA-2003:408 CVE Names: CAN-2002-1574 CAN-2003-0700 CAN-2004-0003 - ---------------------------------------------------------------------

1. Topic:

Updated kernel packages are now available that fix a few security issues, an NFS performance issue, and an e1000 driver loading issue introduced in Update 3.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - athlon, i386, i686 Red Hat Enterprise Linux ES version 2.1 - athlon, i386, i686 Red Hat Enterprise Linux WS version 2.1 - athlon, i386, i686

3. Problem description:

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

Alan Cox found issues in the R128 Direct Render Infrastructure that could allow local privilege escalation. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0003 to this issue.

The C-Media PCI sound driver in Linux before 2.4.22 does not use the get_user function to access userspace in certain conditions, which crosses security boundaries. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0700 to this issue.

An overflow was found in the ixj telephony card driver in Linux kernels prior to 2.4.20. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2002-1574 to this issue.

All users are advised to upgrade to these errata packages, which contain backported security patches that corrects these issues. These packages also contain a fix to enhance NFS performance, which was degraded in the last kernel update as part of Update 3.

4. Solution:

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

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs.

Please note that this update is also available via Red Hat Network. Many people find this 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.

If up2date fails to connect to Red Hat Network due to SSL Certificate Errors, you need to install a version of the up2date client with an updated certificate. The latest version of up2date is available from the Red Hat FTP site and may also be downloaded directly from the RHN website:

https://rhn.redhat.com/help/latest-up2date.pxt

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

112766 - e.34 kernel breaks UDP NFS badly 113602 - CAN-2004-0003 r128 DRI 113305 - CAN-2003-0700 CMedia additional get_user issues 113300 - CAN-2002-1574 ixj telephony card driver overflow 112914 - After upgraded the latest kenerl e.34 or e.35, the Intel Pro/100 module did not load during the reboot. 113498 - modules.dep points to the wrong driver
