Debian GNU/Linux Advisory: jnethack

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.
