This release clears CVE-2021-40530 and fixes a problem with ChaCha20 AVX2 implementation. The CVE was due to ElGamal encryption using a work estimate to size encryption exponents instead subgroup order. The ChaCha20 issue was due to mishandling a carry in the AVX2 code path. The ChaCha20 issue was difficult to duplicate, so most users should not experience it. https://github.com/weidai11/cryptopp/releases/tag/CRYPTOPP_8_6_0 Signed-off-by: Fabrice Fontaine <fontaine.fabrice@gmail.com> Signed-off-by: Yann E.
