Legality of src:console-cyrillic (claims "public domain" but I don't think this can be done in the Russian Federation and Kazachstan)?

[наб]

Hi!

Looking at https://sources.debian.org/src/console-cyrillic/0.9-17.3, I see:

(CAG is an uncopyrightable bitmap font so whatever.)

AFAICT this software was produced in the Russian Federation and Kazachstan,
on this side of the millenium (after both signed the Berne convention),
with no explicit licence given, and it's not yet been 70 years.
I haven't found anything that would indicate that dedicating a work
to the public domain is possible in these jurisdixions,
so these look undistributable to me?

The d-legal archives don't really speak on this AFAICT.
