Selain merilis update untuk Insiders, Microsoft juga merilis update untuk semua versi Windows 10 yang telah rilis sebelumnya. Sama dengan update untuk Insiders, update ini juga menargetkan pada celah keamanan yang ditemukan sebelumnya (CVE-2020-0601).

CVE-2020-0601

A spoofing vulnerability exists in the way Windows CryptoAPI (Crypt32.dll) validates Elliptic Curve Cryptography (ECC) certificates.

An attacker could exploit the vulnerability by using a spoofed code-signing certificate to sign a malicious executable, making it appear the file was from a trusted, legitimate source. The user would have no way of knowing the file was malicious, because the digital signature would appear to be from a trusted provider.

A successful exploit could also allow the attacker to conduct man-in-the-middle attacks and decrypt confidential information on user connections to the affected software.

The security update addresses the vulnerability by ensuring that Windows CryptoAPI completely validates ECC certificates.
