Summary
Red Hat Security Advisory: ruby193-ruby security update
Notes
Topic
Updated ruby193-ruby packages that fix one security issue are now available
for Red Hat Software Collections 1.
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.
Details
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
CVE-2013-4287. Upstream acknowledges Damir Sharipov as the original
reporter.
All ruby193-ruby users are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue.
