<p>A security feature bypass vulnerability exists when Microsoft .NET Framework (and .NET Core) components do not completely validate certificates.</p> <p>An attacker could present a certificate that is marked invalid for a specific use, but the component uses it for that purpose. This action disregards the Enhanced Key Usage taggings.</p> <p>The security update addresses the vulnerability by helping to ensure that .NET Framework (and .NET Core) components completely validate certificates.</p>
