Red Hat 2003-416 Security Check

High Log Correlation Engine Plugin ID 801585


The remote host is missing a security update.


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
( 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.


Update the affected package(s).
