Package        : cabextract
Vulnerability  : missing directory sanitising
Problem-Type   : remote
Debian-specific: no
CVE ID         : CAN-2004-0916
Debian Bug     : 277522

The upstream developers discovered a problem in cabextract, a tool to
extract cabinet files.  The program was able to overwrite files in
upper directories.  This could lead an attacker to overwrite arbitrary
files.

For the stable distribution (woody) this problem has been fixed in
version 0.2-2b.

For the unstable distribution (sid) this problem has been fixed in
version 1.1-1.

We recommend that you upgrade your cabextract 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.
