RHEL 2.1 : kernel (RHSA-2003:389)

high Nessus Plugin ID 12438

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 allowing local users to gain root privileges.

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

A flaw in bounds checking in the do_brk() function in the Linux kernel versions 2.4.22 and previous can allow a local attacker to gain root privileges. This issue is known to be exploitable; an exploit has been seen in the wild that takes advantage of this vulnerability. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2003-0961 to this issue.

All users of Red Hat Enterprise Linux 2.1 are advised to upgrade to these errata packages, which contain a backported security patch that corrects this vulnerability.

Users of Red Hat Enterprise Linux 3 should upgrade to the kernel packages provided by RHBA-2003:308 (released on 30 October 2003), which already contained a patch correcting this issue.

Solution

Update the affected packages.
