Red Hat 2004-066 Security Check

high Log Correlation Engine Plugin ID 801589

Synopsis

The remote host is missing a security update.

Description

Updated kernel packages that fix a security vulnerability that may
allow local users to gain root privileges 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 allow a
local attacker to gain root privileges. 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.

Solution

Update the affected package(s).
