Description: Ruby is an extensible, interpreted, object-oriented, scripting language. It has features to process text files and to do system management tasks. A flaw was found in Ruby's SSL client's hostname identity check when handling certificates that contain hostnames with NULL bytes. An attacker could potentially exploit this flaw to conduct man-in-the-middle attacks to spoof SSL servers. Note that to exploit this issue, an attacker would need to obtain a carefully-crafted certificate signed by an authority that the client trusts. (CVE-2013-4073) All users of Ruby are advised to upgrade to these updated packages, which contain backported patches to resolve this issue. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network.
