Technical details

(8) CVE-2020-0601 The certificate validation vulnerability exists in the way Windows CryptoAPI (Crypt32.dll) validates Elliptic Curve Cryptography (ECC) certificates. It could allow an adversary to spoof a code-signing or TLS certificate and have it appear as valid, in addition this vulnerability may allow remote code execution. This Microsoft security patch also creates a new log event with event ID 1 in the Windows Application event log to record the attempted exploitation of this vulnerability.
