- A flaw exists in the way .NET handles DLL files that can be exploited by an attacker to execute arbitrary code.
(CVE-2012-2519)

- A remote code execution vulnerability exists in the way the .NET Framework retrieves the default web proxy settings. (CVE-2012-4776)

- A flaw exists in the way .NET validates permissions for objects involved with reflection could be exploited by an attacker to gain complete control of an affected system. (CVE-2012-4777)
