Lol .. limited cypher keys .. err.. oops ...
Luckily it's limited to Debian & debian derivatives

and really only affects servers, as they will be generating & distributing keys .. not the general desktop user.
*But Wait! There's still more!
Um, the problem is ... how many corporations are running Debian, or Debian Derivative, servers - Debain is the "Stable release" of the linux world. This problem doesn't just affect Linux users!!!!! It affects anyone which uses a compromised server!!!!!
This problem affects anyone using a debian server -> Anyone using netbanking ever asked their bank what server OS they're using to serve their internet banking site?
Be afraid .. be very afraid

Even if you are running windows.
