Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In xous has unsound usages of `core, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

We consider `as_slice` and `as_slice_mut` unsound because: the pointer with any bit patterns could be cast to the slice of arbitrary types. The pointer could be created by unsafe new and deprecated `from_parts`. We consider that `from_parts` should be removed in latest version because it will help trigger unsoundness in `as_slice`. With new declared as unsafe, `as_slice` should also declared as unsafe. This was patched in by marking two functions as `unsafe`.
