Summary

Ruby is an extensible, interpreted, object-oriented, scripting language. It has features to process text files and to do system management tasks. RubyGems is the Ruby standard for publishing and managing third-party libraries.
It was discovered that the rubygems API validated version strings using an unsafe regular expression. An application making use of this API to process a version string from an untrusted source could be vulnerable to a denial of service attack through CPU exhaustion. (CVE-2013-4287)
Red Hat would like to thank Rubygems upstream for reporting this issue. Upstream acknowledges Damir Sharipov as the original reporter.
Users of Red Hat OpenStack 3.0 are advised to upgrade to these updated packages, which correct this issue.
