Synopsis:          mopd-linux buffer overflow
Advisory ID:       RHSA-2000:050-01
Issue date:        2000-08-08
Updated on:        2000-08-08
Product:           Red Hat Powertools
Keywords:          N/A

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.

5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):

N/A

6. RPMs required:

Red Hat Powertools 6.2:

sparc:
ftp://updates.redhat.com/powertools/6.2/sparc/mopd-linux-2.5.3-15.sparc.rpm

alpha:
