The remote Red Hat host is missing one or more security updates.
Updated kernel packages for Red Hat Enterprise Linux 3 that fix
security vulnerabilities are now available.
The Linux kernel handles the basic functions of the operating system.
A flaw was found in Linux kernel versions 2.4 and 2.6 for x86 and
x86_64 that allowed local users to cause a denial of service (system
crash) by triggering a signal handler with a certain sequence of fsave
and frstor instructions. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CVE-2004-0554 to this
Another flaw was discovered in an error path supporting the clone()
system call that allowed local users to cause a denial of service
(memory leak) by passing invalid arguments to clone() running in an
infinite loop of a user's program. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2004-0427
to this issue.
Enhancements were committed to the 2.6 kernel by Al Viro which enabled
the Sparse source code checking tool to check for a certain class of
kernel bugs. A subset of these fixes also applies to various drivers
in the 2.4 kernel. Although the majority of these resides in drivers
unsupported in Red Hat Enterprise Linux 3, the flaws could lead to
privilege escalation or access to kernel memory. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
name CVE-2004-0495 to these issues.
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. These packages contain
backported patches to correct these issues.
