Windows Kernel integer overflows in registry subkey lists leading to memory corruption

A couple integer overflows in the the Windows Kernel through the registry, the core problem being that a 16bit integer is used for the Count field storing the number of subkeys inside an index.Under normal circumstances, when adding new subkeys the registry will automatically divide itself so you won’t have more than ~1000 subkeys, but you can import arbitrarily formatted indexes, using this you can craft one with 65535 keys…
