Yes.

More precisely, they can spend a lot of effort to break Diffie-Hellman
for a small number of primes. Unfortunately, most implementations only
use a small set of commonly used primes.

Tinc 1.1 uses elliptic curve Diffie-Hellman (ECDH). This, as far as I
know, has not been broken by the NSA. Tinc 1.0 doesn't use
Diffie-Hellman at all.
