Treat the debug offset tables read from a target process as untrusted input and validate them before the unwinder uses any reported sizes or offsets. Add a shared validator in debug_offsets_validation.h and run it once when _Py_DebugOffsets is loaded and once when AsyncioDebug is loaded. The checks cover section sizes used for fixed local buffers and every offset that is later dereferenced against a local buffer or local object view. This keeps the bounds checks out of the sampling hot path while rejecting malformed tables up front. |
