An updated ruby package that fixes a denial of service issue for the CGI instance is now available. [Updated 17 Jan 2005] Errata has been updated to include 32-bit libraries on 64-bit architectures.
Ruby is an interpreted scripting language for object-oriented programming. A flaw was dicovered in the CGI module of Ruby. If empty data is sent by the POST method to the CGI script which requires MIME type multipart/form-data, it can get stuck in a loop. A remote attacker could trigger this flaw and cause a denial of service. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0983 to this issue. Users are advised to upgrade to this erratum package, which contains a backported patch to cgi.rb.
