Updated kernel for Red Hat Linux resolves security vulnerability
(Click here to view the original thread with full colors/images)
Posted by: Canis Lupus
Updated kernel packages for Red Hat Linux are now available that fix a security vulnerability in which may allow local users to gain root privileges.
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 CAN-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.
