  20.   An updated ruby package that fixes a denial of service issue for the CGI     
  21.   instance is now available.

  23.   Ruby is an interpreted scripting language for object-oriented programming.

  25.   A flaw was dicovered in the CGI module of Ruby. If empty data is sent by     
  26.   the POST method to the CGI script which requires MIME type                   
  27.   multipart/form-data, it can get stuck in a loop. A remote attacker could     
  28.   trigger this flaw and cause a denial of service. The Common                  
  29.   Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name  
  30.   CAN-2004-0983 to this issue.                                                 
  31.                                                                                
  32.   Users are advised to upgrade to this erratum package, which contains a       
  33.   backported patch to cgi.rb.
