Description

The remote host is affected by the vulnerability described in GLSA-200801-17 (Netkit FTP Server: Denial of Service)

 Venustech AD-LAB discovered that an FTP client connected to a vulnerable server with passive mode and SSL support can trigger an fclose() function call on an uninitialized stream in ftpd.c.

 A remote attacker can send specially crafted FTP data to a server with passive mode and SSL support, causing the ftpd daemon to crash.
 Workaround :

 Disable passive mode or SSL.

Solution
