First Patch Tuesday updates for 2020 are scheduled for today, and it appears some "extraordinarily serious security vulnerability" is going to be addressed. Today was already an important day for patches since these will be the last updates being shipped for Windows 7. However, things are getting more serious as reports suggest Microsoft has already shipped bug fixes to the US military and other high-value customers and targets managing Internet infrastructure.

While there is no confirmation from the Redmond software maker at this point and we are waiting for the patches to drop to hopefully get more details, industry insiders suggest that the vulnerability resides in the Windows component crypt32.dll. This module, according to Microsoft, handles "certificate and cryptographic messaging functions in the CryptoAPI," the API that enables developers to secure apps.
