the References section.

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 Red Hat OpenShift Enterprise 1.2.2 are advised to upgrade to
these updated packages, which resolve this issue.


Before applying this update, make sure all previously released errata
