RHEL 3 : kernel (RHSA-2003:416)

high Nessus Plugin ID 12443

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated kernel packages are now available that fix a security vulnerability which may allow local users to gain root privileges.

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

Paul Starzetz discovered a flaw in bounds checking in mremap() in the Linux kernel versions 2.4.23 and previous which may allow a local attacker to gain root privileges. No exploit is currently available;
however, it is believed that this issue is exploitable (although not trivially.) The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2003-0985 to this issue.

All users of Red Hat Enterprise Linux 3 are advised to upgrade to these errata packages, which contain a backported security patch that corrects this issue.

Red Hat would like to thank Paul Starzetz from ISEC for disclosing this issue as well as Andrea Arcangeli and Solar Designer for working on the patch.

Solution

Update the affected packages.
