Two unchecked buffer conditions exists in the WebBBS software located in the search function and in the new user signup function.
By using an overly long search string it is possible to cause a denial of service attack against a remote server. In addition, by sending a user name of 896 bytes (user name + EIP pointer) a buffer overrun will occur, thereby allowing an intruder to run code on the remote system.
