CVE-2020-0601

A serious issue in the way Windows handles digital certificates.

Here's a quick mathematical explanation of the issue:

The bug exploits crypt32.dll signature verification on elliptic curve. crypt32.dll only checks for matching public key and parameters, but not the generator G.
The private key is d = [1, n - 1], where n is order of the curve
The public key is Q = dG.
The generator G is defined for each curve, but the bug allows your to specify your own generator.
