Synopsis

Moderate: ruby193-rubygem-activerecord security update

Type/Severity

Security Advisory Moderate

Topic

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.

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.
