Hi,
The following vulnerability was published for pure-ftpd.
CVE-2021-40524[0]:
| In Pure-FTPd 1.0.49, an incorrect max_filesize quota mechanism in the
| server allows attackers to upload files of unbounded size, which may
| lead to denial of service or a server hang. This occurs because a
| certain greater-than-zero test does not anticipate an initial -1
| value.
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.
Regards,
Salvatore
