Subject: [gentoo-project] Nitrokey Pro not vulnerable to the Nitrokey Start read-only bit

TL;DR: The Foundation/Nitrokey partnership is sending Nitrokey Pro units
that are not the same as the Nitrokey Start units vulnerable to hands-on
key extraction attack.

As a few people have asked about it:
There was a production batch of "Nitrokey Start" units that did not have
a read-protection bit configured, and thus were vulnerable to a key
extraction attack:
https://github.com/rot42/gnuk-extractor
The issue was specific to a batch of hardware that was mis-programmed,
and the issue is not present on newer Nitrokey Start units.
https://github.com/Nitrokey/nitrokey-start-firmware/issues/14

The Foundation/Nitrokey partnership is providing Nitrokey Pro 2 units,
which are supposedly not vulnerable to this issue (but I'd be happy for
a hardware hacker to confirm this, I understand that the Pro2 has a
seperate smartcard internally)

If you already had an older Nitrokey Start unit, reviewing/updating the
firmware is advised.
