RHSA-2013:1441: Moderate: rubygems security update

First published: Thu Oct 17 2013(Updated: )

RubyGems is the Ruby standard for publishing and managing third-party<br>libraries.<br>It was found that RubyGems did not verify SSL connections. This could lead<br>to man-in-the-middle attacks. (CVE-2012-2126)<br>It was found that, when using RubyGems, the connection could be redirected<br>from HTTPS to HTTP. This could lead to a user believing they are installing<br>a gem via HTTPS, when the connection may have been silently downgraded to<br>HTTP. (CVE-2012-2125)<br>It was discovered that the rubygems API validated version strings using an<br>unsafe regular expression. An application making use of this API to process<br>a version string from an untrusted source could be vulnerable to a denial<br>of service attack through CPU exhaustion. (CVE-2013-4287)<br>Red Hat would like to thank Rubygems upstream for reporting CVE-2013-4287.<br>Upstream acknowledges Damir Sharipov as the original reporter.<br>All rubygems users are advised to upgrade to this updated package, which<br>contains backported patches to correct these issues.<br>
