1. Summary:

An updated kdbg package that fixes a minor security issue is 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

3. Problem description:

Kdbg is a K Desktop Environment (KDE) GUI for gdb, the GNU debugger.

Kdbg 1.1.0 through 1.2.8 does not check permissions of the .kdbgrc file.
If a program is located in a world-writable location, it is possible for a
local user to inject malicious commands.  These commands are then executed
with the permission of any user that runs Kdbg.  The Common Vulnerabilities
and Exposures project assigned the name CAN-2003-0644 to this issue.

Users of Kdbg should upgrade to this updated package, which contains a
backported patch to correct this issue.
