- ---------------------------------------------------------------------1. Summary:

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64
Red Hat Linux Advanced Workstation 2.1 - ia64
Red Hat Enterprise Linux ES version 2.1 - i386
Red Hat Enterprise Linux WS version 2.1 - i386

3. Problem description:

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.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via Red Hat Network.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
