CVE-2007-6740

The ftp_STOU function in FTPServer.py in pyftpdlib before 0.2.0 does not limit the number of attempts to discover a unique filename, which might allow remote authenticated users to cause a denial of service via a STOU command.

Does this matter?

Lower severity and a low EPSS score (1.75%). Track it; it rarely justifies an emergency change on its own.
