NVD Description

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

setuptools is a package that allows users to download, build, install, upgrade, and uninstall Python packages. Prior to 83.0.0, FileList applied MANIFEST.in exclude, global-exclude, recursive-exclude, and prune directives by matching compiled glob patterns against on-disk file names without Unicode normalization, so on macOS APFS or HFS+ an NFD file name could bypass an NFC exclusion rule and be packed into a source distribution. This issue is fixed in version 83.0.0.
