PyO3 has an Out-of-bounds Read in `nth` / `nth_back` for `PyList` and `PyTuple` iterators

PyO3 0.24.0 added optimized implementations of Iterator::nth and DoubleEndedIterator::nthback for the BoundListIterator and BoundTupleIterator types. These implementations computed the target index using unchecked usize addition index + n before bounds-checking against the sequence length, then...

PyO3 has type confusion when accessing data from sublasses of subclasses of native types with `abi3` feature

PyO3 0.28.1 added support for pyclassextends=PyList struct NativeSub and other native types when targeting Python 3.12 and up with the abi3 feature. It was discovered that subclasses of such classes would use the type of the subclass when attempting to access to data of NativeSub contained within...
