The remote host is affected by the vulnerability described in GLSA-200502-27 (gFTP: Directory traversal vulnerability)
gFTP lacks input validation of filenames received by remote servers.

An attacker could entice a user to connect to a malicious FTP server and conduct a directory traversal attack by making use of specially crafted filenames. This could lead to arbitrary files being created or overwritten.
Workaround :
There is no known workaround at this time.
