Microsoft Java Virtual Machine (for Windows 95/98/ME/NT4) Build 3319

The Microsoft Virtual Machine (Microsoft VM) is a platform-independent software engine that runs Java applets, applications, and COM objects. The Microsoft VM is an interpreter and a runtime system. As an interpreter, the Microsoft VM interprets architecture-neutral instructions, or bytecode. Bytecode is machine-independent code generated by Java compilers, such as jvc.exe or the Microsoft compiler, and executed by the Java interpreter or compiled, at the last minute, by a JIT compiler. This release of the Microsoft VM (build 3319) is for machines with Microsoft Internet Explorer 4.01 or later. This latest update eliminates a new variant of VM File Reading Vulnerability. Once installed, the Microsoft VM cannot be uninstalled.
