"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.");
