CVE-2020-11735
The private-key operations in ecc.c in wolfSSL before 4.4.0 do not use a constant-time modular inverse when mapping to affine coordinates, aka a "projective coordinates leak."

Does this matter?
Lower severity and a low EPSS score (1.29%). Track it; it rarely justifies an emergency change on its own.
