Red Hat: 2014:0207-01: rubygems: Moderate Advisory
Summary
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.
All users of Red Hat OpenShift Enterprise 2.0.2 are advised to upgrade to
this updated package, which contains a backported patch to correct this
issue.
