Name of the Vulnerable Software and Affected Versions
websocket-driver versions prior to 0.8.2
Description
Remote clients can crash a TCP-backed WebSocket server by sending a malformed
Host header. The WebSocket::Driver.server() method passes this header to URI.parse in the lib/websocket/http/request.rb file without catching the URI::InvalidURIError exception. If the application using the library does not handle this error from the parse() function, the server process will crash.Recommendations
Update websocket-driver to version 0.8.2.
