The ecc_256_modq function in ecc-256.c in Nettle before 3.2 does not
properly handle carry propagation and produces incorrect output in its
implementation of the P-256 NIST elliptic curve, which allows attackers to
have unspecified impact via unknown vectors, a different vulnerability than
CVE-2015-8803.
