1. Topic:

A buffer overflow has been discovered in all releases of
mopd-linux included in the 6.0, 6.1, and 6.2 releases of
Powertools.

2. Relevant releases/architectures:

Red Hat Powertools 6.0 – i386, alpha, sparc
Red Hat Powertools 6.1 – i386, alpha, sparc
Red Hat Powertools 6.2 – i386, alpha, sparc

3. Problem description:

This vulnerability allows long file names to be sent from the
client to the server, causing the buffer overflow.

The server also used filenames supplied from the client directly
as a part of a format string in a syslog function call.

4. Solution:

For each RPM for your particular architecture, run:

rpm -Fvh [filename]

where filename is the name of the RPM.
