This signature detects attempts to exploit a known vulnerability in the Microsoft .NET Framework. A successful attack can result in a denial-of-service condition.
Microsoft .NET Framework 2.0 SP2, 3.5, 3.5 SP1, 3.5.1, 4, and 4.5 does not properly parse a DTD during XML digital-signature validation, which allows remote attackers to cause a denial of service (application crash or hang) via a crafted signed XML document, aka "Entity Expansion Vulnerability."
