Microsoft releases ‘Shim’ to counter IE Attacks

Shim is a term used to describe an application compatibility workaround. Microsoft’s workaround used the Application Compatibility Toolkit to modify the core library of IE — a DLL, or Dynamic-Link library, named “Mshtml.dll,” that contains the rendering engine — in memory each time IE runs. The modification prevents recursive loading of a CSS, which effectively stops the existing attacks.
