If data tainting is implemented the only way for taint information to propagate is by data access The Windows Registry is a hierarchical database that is used to store information regarding the system and its users gerridae we keep the base address and the size of the modules that we are interested in When target instructions refer to memory locations for their operands it is the task of the emulated CPU to convert the virtual addresses to their physical correspondants The object header itself might consist of up to five header fields that are used to describe the object Together with COMs version management that utilizes the Windows registry as well this enables client components to react to new versions in a sensible way gerridaeTo summarize the only information a client has on an interface is the location of the virtual table in memory and what functions it provides The operating system itself is run in a privileged mode on the CPU called the kernel mode, whereas the applications run in unprivileged user mode instruction a software interrupt is generated in the CPU In this mode all virtual disk images are used in a read only fashion and sectors that are written are stored in temporary files Another task the virtual memory manager is responsible for is to perform paging plasmatron-Ing
