RHSA-2003-419: kernel

Vulnerability Assessment Summary
Check for the version of the kernel packages

Detailed Explanation for this Vulnerability Assessment

Updated kernel packages are now available that fix a security
vulnerability which may permit local users to gain root rights.

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 permit a local attacker to
gain root rights. 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.
