DESCRIPTION:
A vulnerability has been reported in Xlight FTP Server, which can be
exploited by malicious users to cause a DoS (Denial of Service).

The vulnerability is caused due to the SFTP/SSH2 virtual server
restricting access of files to the user who opens the files first.
This can be exploited to render the files inaccessible to other
users.

The vulnerability is reported in versions prior to 3.7.2.
