As a note: not just Debian or derived systems; anything that was
accessed from an insecure system, or that used a key generated on an
insecure system, is at risk here.

Not all keys, only those that were generated on the insecure machine.
Mine were safe (yay) because I generated them before the problematic
patches were added to Debian and never rolled them over (boo).

Anything using OpenSSL to perform SSL, SSH or other encryption is at
risk.  That covers the vast majority of packages, especially as SSL keys
are almost exclusively documented to be generated with OpenSSL.
