Red Hat Product Errata RHSA-2003:419 0 high SHIPPED_LIVE Important: kernel security update 2004-01-05 05:00:00 UTC

Description Mark J. Cox 2004-01-05 12:55:17 UTC 
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.
