Updated ruby packages that fix a denial of service issue for the CGI
instance are now available.
This update has been rated as having moderate security impact by the Red
Hat Security Response Team.
Ruby is an interpreted scripting language for object-oriented programming.
A flaw was discovered in the way Ruby's CGI module handles certain
multipart/form-data MIME data. If a remote attacker sends a specially
crafted multipart-form-data request, it is possible to cause the ruby
CGI script to enter an infinite loop, causing a denial of service.
Users of Ruby should upgrade to these updated packages which contain
backported patches and are not vulnerable to these issues.
