reseed(8) performs a unsecured HTTP request to random.org for its
bits, despite random.org offering HTTPS services.

https doesn't help if your host entropy pool is poorly seeded.
[SSL/TLS needs entropy for authenticity/privacy.]


The Ubuntu Security Team took no interest when contacted by email (no
reply); the point of contact listed in the man pages took no interest
when contacted by email (no reply); and a launcher bug report was not
acted upon (https://bugs.launchpad.net/ubuntu/+source/reseed/+bug/804594).

you're surprised?
