Package        : unzip
Vulnerability  : directory traversal
Problem-Type   : local
Debian-specific: no
CVE Ids        : CAN-2003-0282

A directory traversal vulnerability in UnZip 5.50 allows attackers to
bypass a check for relative pathnames ("../") by placing certain invalid
characters between the two "." characters.

For the stable distribution (woody) this problem has been fixed in
version 5.50-1woody1.

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

We recommend that you update your unzip 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.
