Debian Security Advisory DSA 316-3                     security@...ian.org

- --------------------------------------------------------------------------

Package        : jnethack
Vulnerability  : buffer overflow, incorrect permissions
Problem-Type   : local
Debian-specific: no
CVE Id         : CAN-2003-0358 CAN-2003-0359

The jnethack package is vulnerable to a buffer overflow exploited via a
long '-s' command line option.  This vulnerability could be used by an
attacker to gain gid 'games' on a system where jnethack is installed.

Additionally, some setgid binaries in the jnethack package have
incorrect permissions, which could allow a user who gains gid 'games'
to replace these binaries, potentially causing other users to execute
malicious code when they run jnethack.

For the stable distribution (woody) these problems have been fixed in
version 1.1.5-11woody2.

For the old stable distribution (potato) these problems have been
fixed in version 1.1.3-4potato1.

For the unstable distribution (sid) these problems are fixed in
version 1.1.5-15.

We recommend that you update your jnethack 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.
