Fedora Core 1 : kernel-2.4.22-1.2138.nptl (2003-046)

high Nessus Plugin ID 13669

Synopsis

The remote Fedora Core 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.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected packages.
