Fedora 2003-046 Security Check

High Log Correlation Engine Plugin ID 801544

Synopsis

The remote host is missing a security update.

Description

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 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.

These packages also contain a fix for a minor information leak in the
real time clock (rtc) routines. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2003-0984
to this issue.

Solution

Update the affected package(s).
