NVD Description

Note: Versions mentioned in the description apply only to the upstream k8s-sidecar package and not the k8s-sidecar package as distributed by Wolfi. See How to fix? for Wolfi 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.
