=====================================================================
1. Summary:
Updated ruby193-ruby packages that fix one security issue are now available
for Red Hat OpenShift Enterprise 1.2.2.
The Red Hat Security Response Team has rated this update as having moderate
security impact. A Common Vulnerability Scoring System (CVSS) base score,

the References section.
2. Relevant releases/architectures:
RHOSE Infrastructure 2.1 - noarch, x86_64
RHOSE Node 1.2 - noarch, x86_64
3. 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 Red Hat OpenShift Enterprise 1.2.2 are advised to upgrade to
these updated packages, which 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. Details on how to
