Red Hat Security Advisory 2013-0548-01 - Red Hat CloudForms is an on-premise hybrid cloud Infrastructure-as-a-Service product that lets you create and manage private and public clouds. It provides self-service computing resources to users in a managed, governed, and secure way. Three flaws were found in rubygem-rack. A remote attacker could use these flaws to perform a denial of service attack against applications using rubygem-rack. It was found that documentation created by rubygem-rdoc was vulnerable to a cross-site scripting attack. If such documentation was accessible over a network, and a remote attacker could trick a user into visiting a specially-crafted URL, it would lead to arbitrary web script execution in the context of the user's session. As rubygem-rdoc is used for creating documentation for Ruby source files, it is not a common scenario to make such documentation accessible over the network.
