FreeBSD : nettle 3.7.2 -- fix serious ECDSA signature verify bug (80f9dbd3-8eec-11eb-b9e8-3525f51429a0)

Niels Moller reports : I've prepared a new bug-fix release of Nettle, a low-level cryptographics library, to fix a serious bug in the function to verify ECDSA signatures. Implications include an assertion failure, which could be used for denial-of-service, when verifying signatures on the secp224...
