Description:Summary:
The remote host is missing an update for the 'ruby'
package(s) announced via the referenced advisory.

Vulnerability Insight:
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.

Affected Software/OS:
ruby on Red Hat Enterprise Linux (v. 5 server)

Solution:
Please Install the Updated Packages.

CVSS Score:
