"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.

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 CVE-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 CVE-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 CVE-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."
