Package        : fuzz
Vulnerability  : privilege escalation
Problem-Type   : local
Debian-specific: no

Joey Hess discovered that fuzz, a software stress-testing tool,
creates a temporary file without taking appropriate security
precautions.  This bug could allow an attacker to gain the privileges
of the user invoking fuzz, excluding root (fuzz does not allow itself
to be invoked as root).

For the stable distribution (woody) this problem has been fixed in
version 0.6-6woody1.

The old stable distribution (potato) does not contain a fuzz package.

For the unstable distribution (sid) this problem will be fixed soon.

We recommend that you update your fuzz package.

Upgrade Instructions
--------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
