Red Hat 2003-389 Security Check

high Log Correlation Engine Plugin ID 801583

Synopsis

The remote host is missing a security update.

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 package(s).
