High Nessus Plugin ID 74300
SynopsisThe remote Red Hat host is missing a security update.
DescriptionUpdated packages for JBoss Enterprise Application Platform 5.2.0 which fix one security issue and one bug are now available for Red Hat Enterprise Linux 4, 5, and 6.
The Red Hat Security Response Team has rated this update as having Important 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.
JBoss Enterprise Application Platform is a platform for Java applications, which integrates the JBoss Application Server with JBoss Hibernate and JBoss Seam.
It was found that the secure processing feature of Xalan-Java had insufficient restrictions defined for certain properties and features.
A remote attacker able to provide Extensible Stylesheet Language Transformations (XSLT) content to be processed by an application using Xalan-Java could use this flaw to bypass the intended constraints of the secure processing feature. Depending on the components available in the classpath, this could lead to arbitrary remote code execution in the context of the application server running the application that uses Xalan-Java. (CVE-2014-0107)
This update also fixes the following bug :
It was observed that when using the Transfomer to convert a StreamSource to DOMResult, the performance of the conversion degraded as the size of the character data increased. For example, converting a 50 MB XML BLOB would take a very long time to finish. This issue has been resolved in this release by adjusting both the SAX2DOM and DOMBuilder classes to handle larger inputs more efficiently.
All users of JBoss Enterprise Application Platform 5.2.0 on Red Hat Enterprise Linux 4, 5, and 6 are advised to upgrade to these updated packages. The JBoss server process must be restarted for the update to take effect.
SolutionUpdate the affected xalan-j2 package.
