An updated rubygems package that fixes one security issue is now available for Red Hat OpenShift Enterprise 2.0.2.

The Red Hat Security Response Team has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

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.

Red Hat would like to thank Rubygems upstream for reporting this issue. Upstream acknowledges Damir Sharipov as the original reporter.
