Synopsis

Moderate: ruby security update

Type/Severity

Security Advisory Moderate

Topic

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.

Description

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.

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.
