The remote host is running Drag And Zip - a file compression utility.

There is a flaw in this program which may allow a remote attacker to
execute arbitrary code on this host.

To exploit this flaw, an attacker would need to craft a special
Zip file and send it to a user on this host. Then, the user would
need to open it using Drag And Zip.

Solution : None
Risk Factor : Low";
