NVD Description

Note: Versions mentioned in the description apply only to the upstream py3-jupyterlab package and not the py3-jupyterlab package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

uuid is for the creation of RFC9562 (formerly RFC4122) UUIDs. Prior to 14.0.0, v3, v5, and v6 accept external output buffers but do not reject out-of-range writes (small buf or large offset). This allows silent partial writes into caller-provided buffers. This vulnerability is fixed in 14.0.0.
