Symptoms
Consider the following scenario:
-
You create a Microsoft .NET Framework 3.5-based application on a computer that is running Windows 7 or Windows Server 2008 R2.
-
The application passes a zero-length byte array to the ICryptoTransform.TransformFinalBlock API to perform a cryptographic operation. For example, you use the API to encrypt or decrypt data.
In this scenario, the application crashes. Additionally, an error message that resembles the following is logged in the event log:
Source: .NET Runtime
Event ID: 1023
Event Data: .NET Runtime version '<2.0.50727.xxxx>' - Fatal Execution Engine Error ('<000007FEFxxxxxxx>') (80131506)
Cause
This issue occurs because the ICryptoTransform.TransformFinalBlock API does not handle the zero-length byte array parameter correctly in the .NET Framework 3.5-based application. Therefore, this results in an unhandled Access Violation exception, which causes the application to crash.
