A flaw was found in Visual Studio. This vulnerability allows an unauthenticated remote attacker to achieve arbitrary code execution by convincing a user to process maliciously crafted data. By exploiting unsafe deserialization (the process of converting stored data back into an active program object), an attacker can execute arbitrary commands with the privileges of the affected application.
