"Updated dump packages that address two security issues are now
available for Red Hat Enterprise Linux 2.1.

This update has been rated as having low security impact by the Red
Hat Security Response Team.

Dump examines files in a file system, determines which ones need to be
backed up, and copies those files to a specified disk, tape, or other
storage medium.

A flaw was found with dump file locking. A malicious local user could
manipulate the file lock in such a way as to prevent dump from
running. The Common Vulnerabilities and Exposures project
(cve.mitre.org) assigned the name CVE-2002-1914 to this issue.

Users of dump should upgrade to these erratum packages, which contain
a patch to resolve this issue."
