DESCRIPTION:
A vulnerability has been discovered in ftpcopy, which can be
exploited by malicious people to conduct script insertion attacks.

The vulnerability is caused due to the "ftpls" command not properly
sanitising the filenames when generating directory listings in HTML
format, which can be exploited to inject arbitrary HTML and script
code, which will be executed in a user's browser session in context
of an affected site when the malicious data is being viewed.

The vulnerability is confirmed in version 0.6.7. Other versions may
also be affected.

SOLUTION:
Do not generate HTML directory listings of untrusted servers.

PROVIDED AND/OR DISCOVERED BY:
Reported in a Debian bug by "non customers".
