1. Summary:

Updated ruby193-rubygem-activerecord packages that fix one security issue
are now available for Red Hat OpenShift Enterprise 1.1.3.

The Red Hat Security Response Team has rated this update as having moderate
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:

3. Description:

Ruby on Rails is a model–view–controller (MVC) framework for web
application development. Active Record implements object-relational mapping
for accessing database entries using objects.

A flaw was found in the way hashes were handled in certain queries. A
remote attacker could use this flaw to perform a denial of service
(resource consumption) attack by sending specially-crafted queries that
would result in the creation of Ruby symbols, which were never garbage
collected. (CVE-2013-1854)

Red Hat would like to thank Ruby on Rails upstream for reporting this
issue. Upstream acknowledges Ben Murphy as the original reporter.

Users of Red Hat OpenShift Enterprise 1.1.3 are advised to upgrade to these
updated packages, which correct this issue.
