Hi,
The following vulnerability was published for f2fs-tools.
CVE-2020-6070[0]:
| An exploitable code execution vulnerability exists in the file system
| checking functionality of fsck.f2fs 1.12.0. A specially crafted f2fs
| file can cause a logic flaw and out-of-bounds heap operations,

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

[1] https://talosintelligence.com/vulnerability_reports/TALOS-2020-0988
Please adjust the affected versions in the BTS as needed.
Note, I did try to reach out to upstream to isolate the upstream
fixes, but got not repsonse so far. In any case bullseye should
ideally get a newer version, thus the RC severity (ortogonally to it,
the issue wouldbe no-dsa for buster).
Regards,
Salvatore
