Oracle Linux 6 : xerces-j2 (ELSA-2011-0858)

This script is Copyright (C) 2013 Tenable Network Security, Inc.


Synopsis :

The remote Oracle Linux host is missing one or more security updates.

Description :

From Red Hat Security Advisory 2011:0858 :

Updated xerces-j2 packages that fix one security issue are now
available for Red Hat Enterprise Linux 6.

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.

The xerces-j2 packages provide the Apache Xerces2 Java Parser, a
high-performance XML parser. A Document Type Definition (DTD) defines
the legal syntax (and also which elements can be used) for certain
types of files, such as XML files.

A flaw was found in the way the Apache Xerces2 Java Parser processed
the SYSTEM identifier in DTDs. A remote attacker could provide a
specially-crafted XML file, which once parsed by an application using
the Apache Xerces2 Java Parser, would lead to a denial of service
(application hang due to excessive CPU use). (CVE-2009-2625)

Users should upgrade to these updated packages, which contain a
backported patch to correct this issue. Applications using the Apache
Xerces2 Java Parser must be restarted for this update to take effect.
