RHSA-2013:1441: Moderate: rubygems security update

RubyGems is the Ruby standard for publishing and managing third-partylibraries.It was found that RubyGems did not verify SSL connections. This could leadto man-in-the-middle attacks. (CVE-2012-2126)It was found that, when using RubyGems, the connection could be redirectedfrom HTTPS to HTTP. This could lead to a user believing they are installinga gem via HTTPS, when the connection may have been silently downgraded toHTTP. (CVE-2012-2125)It was discovered that the rubygems API validated version strings using anunsafe regular expression. An application making use of this API to processa version string from an untrusted source could be vulnerable to a denialof 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 rubygems users are advised to upgrade to this updated package, whichcontains backported patches to correct these issues.
