Arithmetic over induction variables in loops were not correctly checked for underflow or overflow. As a result, the compiler would allow for invalid indexing to occur at runtime, potentially leading to memory corruption.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
