NVD Description

Note: Versions mentioned in the description apply only to the upstream opal package and not the opal package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. From 45.0.0 to before 46.0.7, if a non-contiguous buffer was passed to APIs which accepted Python buffers (e.g. Hash.update()), this could lead to buffer overflows. This vulnerability is fixed in 46.0.7.
