arbitrary code within the context of the application. Failed attacks may cause

Impact Level: System/Application";

long 'LIST' command. This can be exploited to cause a stack-based buffer
overflow via a specially crafted FTP LIST command.";

General solution options are to upgrade to a newer release, disable respective
features, remove the product or replace the product by another one.";
