CentOS Update for rubygems CESA-2013:1441 centos6

The remote host is missing an update for the 'rubygems' package(s) announced via the referenced advisory.

RubyGems is the Ruby standard for publishing and managing third-party libraries. It was found that RubyGems did not verify SSL connections. This could lead to man-in-the-middle attacks. (CVE-2012-2126) It was found that, when using RubyGems, the connection could be redirected from HTTPS to HTTP. This could lead to a user believing they are installing a gem via HTTPS, when the connection may have been silently downgraded to HTTP. (CVE-2012-2125) 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 rubygems users are advised to upgrade to this updated package, which contains backported patches to correct these issues.
