NVD Description

Note: Versions mentioned in the description apply only to the upstream python3.13 package and not the python3.13 package as distributed by Debian. See How to fix? for Debian:14 relevant fixed versions and status.

During an address list folding when a separating comma ends up on a folded line and that line is to be unicode-encoded then the separator itself is also unicode-encoded. Expected behavior is that the separating comma remains a plan comma. This can result in the address header being misinterpreted by some mail servers.
