Hi,

Ah! That could be a problem then... (having checked by asking on
#debian) "openssl rand ..." was also affected by problem reported in the
Debian Security Advisory.

This means that if any data encryption keys were generated on vulnerable
hosts they need to be regenerated or the data cannot be considered
secure (given the amount of entropy that would have been used).

So, um, don't shoot the messenger! :o)
