Synopsis :

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

Description :

Official ruby site reports :

A 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). The problem is triggered by sending
the library an HTTP request that uses multipart MIME encoding and as
an invalid boundary specifier that begins with '-' instead of '--'.
Once triggered it will exhaust all available memory resources
effectively creating a DoS condition.
