There is no fixed version for Debian:9 pure-ftpd.
NVD Description
Note: Versions mentioned in the description apply only to the upstream pure-ftpd package and not the pure-ftpd package as distributed by Debian.
See How to fix? for Debian:9 relevant fixed versions and status.
In Pure-FTPd before 1.0.50, 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. (Versions 1.0.23 through 1.0.49 are affected.)
