Medium Nessus Plugin ID 23771


The remote FreeBSD host is missing one or more security-related updates.


The official ruby site reports :

Another vulnerability has been discovered in the CGI library (cgi.rb) that ships with Ruby which could be used by a malicious user to create a denial of service attack (DoS).

A specific HTTP request for any web application using cgi.rb causes CPU consumption on the machine on which the web application is running. Many such requests result in a denial of service.


Update the affected packages.
