"Updated kernel packages that fix several security issues in Red Hat
Enterprise Linux 3 are now available.

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

Paul Starzetz discovered flaws in the Linux kernel when handling file
offset pointers. These consist of invalid conversions of 64 to 32-bit
file offset pointers and possible race conditions. A local
unprivileged user could make use of these flaws to access large
portions of kernel memory. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CVE-2004-0415 to this
issue.

These packages contain a patch written by Al Viro to correct these
flaws. Red Hat would like to thank iSEC Security Research for
disclosing this issue and a number of vendor-sec participants for
reviewing and working on the patch to this issue.

In addition, these packages correct a number of minor security 
issues :

An bug in the e1000 network driver. This bug could be used by local
users to leak small amounts of kernel memory (CVE-2004-0535).

A bug in the SoundBlaster 16 code which does not properly handle
certain sample sizes. This flaw could be used by local users to crash
a system (CVE-2004-0178).

A possible NULL pointer dereference in the Linux kernel prior to
2.4.26 on the Itanium platform could allow a local user to crash a
system (CVE-2004-0447).

Inappropriate permissions on /proc/scsi/qla2300/HbaApiNode
(CVE-2004-0587).

All Red Hat Enterprise Linux 3 users are advised to upgrade their
kernels to the packages associated with their machine architectures
and configurations as listed in this erratum."
