Updated ruby packages that fix one security issue are now available for
Red Hat Enterprise Linux 5.

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.

Ruby is an extensible, interpreted, object-oriented, scripting language. It
has features to process text files and to do system management tasks.

It was discovered that Ruby's REXML library did not properly restrict XML
entity expansion. An attacker could use this flaw to cause a denial of
service by tricking a Ruby application using REXML to read text nodes from
specially-crafted XML content, which will result in REXML consuming large
amounts of system memory. (CVE-2013-1821)

All users of Ruby are advised to upgrade to these updated packages, which
contain backported patches to resolve this issue.
