=====================================================================
1. Summary:
Updated ruby193-ruby packages that fix one security issue are now available
for Red Hat OpenStack 3.0.
The Red Hat Security Response Team has rated this update as having critical
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.
2. Relevant releases/architectures:
OpenStack 3 - noarch, x86_64
3. Description:
Ruby is an extensible, interpreted, object-oriented, scripting language.
It has features to process text files and to perform system management
tasks.
A buffer overflow flaw was found in the way Ruby parsed floating point
numbers from their text representation. If an application using Ruby
accepted untrusted input strings and converted them to floating point
numbers, an attacker able to provide such input could cause the application
to crash or, possibly, execute arbitrary code with the privileges of the
application. (CVE-2013-4164)
Users of Red Hat OpenStack 3.0 are advised to upgrade to these updated
packages, which correct this issue.
4. Solution:
Before applying this update, make sure all previously released errata
