Vulnerability Assessment Details

RHSA-2004-066: kernel

Vulnerability Assessment Summary
Check for the version of the kernel packages

Detailed Explanation for this Vulnerability Assessment

Updated kernel packages that fix a security vulnerability that may permit
local users to gain root rights are now available. These packages also
resolve other minor issues.

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

Paul Starzetz discovered a flaw in return value checking in mremap() in the
Linux kernel versions 2.4.24 and previous that may permit a local attacker
to gain root rights. No exploit is currently available
however this
issue is exploitable. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2004-0077 to this issue.

All users are advised to upgrade to these errata packages, which contain
backported security patches that correct these issues.

Red Hat would like to thank Paul Starzetz from ISEC for reporting this issue.

For the IBM S/390 and IBM eServer zSeries architectures, the upstream
version of the s390utils package (which fixes a bug in the zipl
bootloader) is also included.
