If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.

Please adjust the affected versions in the BTS as needed.

Note, I did set the severity here straight to RC as I think the fix
should go in bullseye. I can try to help with a NMU if needed.
