As part of today's "Patch Tuesday", Microsoft addressed a critical flaw in the Windows 10 and Windows Server 2016 version of crypt32.dll. Crypt32.dll implements the Windows CryptoAPI, which provides various cryptographic features used by software to verify digital signatures. This flaw was originally discovered by the NSA, but has not been used in attacks yet.

In this webcast, you will learn more about the nature of the vulnerability, how it could be exploited, and current recommendations to implement the patches as efficiently as possible.
