Package        : xonix
Vulnerability  : failure to drop privileges
Problem-Type   : local
Debian-specific: no
CVE Ids        : CAN-2004-0157

Steve Kemp discovered a vulnerability in xonix, a game, where an
external program was invoked while retaining setgid privileges.  A
local attacker could exploit this vulnerability to gain gid "games".

For the current stable distribution (woody) this problem will be fixed
in version 1.4-19woody1.

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

We recommend that you update your xonix 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.
