CentOS Errata and Security Advisory CESA-2005:583-01
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 CAN-2002-1914 to this issue.
Users of dump should upgrade to these erratum packages, which contain a patch to resolve this issue.
