Package        : catdoc
Vulnerability  : insecure temporary file
Problem-Type   : local
Debian-specific: no
CVE ID         : CAN-2003-0193
Debian Bug     : 183525

A temporary file problem has been discovered in xlsview from the
catdoc suite, convertors from Word to TeX and plain text, which could
lead to local users being able to overwrite arbitrary files via a
symlink attack on predictable temporary file names.

For the stable distribution (woody) this problem has been fixed in
version 0.91.5-1.woody3.

For the unstable distribution (sid) this problem has been fixed in
version 0.91.5-2.

We recommend that you upgrade your catdoc package.


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

wget url
        will fetch the file for you

sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade

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