Oracle Linux 6 : tomcat6 (ELSA-2014-1038)

Medium Nessus Plugin ID 77137


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


From Red Hat Security Advisory 2014:1038 :

Updated tomcat6 packages that fix two security issues are now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Low security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies.

It was found that several application-provided XML files, such as web.xml, content.xml, *.tld, *.tagx, and *.jspx, resolved external entities, permitting XML External Entity (XXE) attacks. An attacker able to deploy malicious applications to Tomcat could use this flaw to circumvent security restrictions set by the JSM, and gain access to sensitive information on the system. Note that this flaw only affected deployments in which Tomcat is running applications from untrusted sources, such as in a shared hosting environment. (CVE-2013-4590)

It was found that, in certain circumstances, it was possible for a malicious web application to replace the XML parsers used by Apache Tomcat to process XSLTs for the default servlet, JSP documents, tag library descriptors (TLDs), and tag plug-in configuration files. The injected XML parser(s) could then bypass the limits imposed on XML external entities and/or gain access to the XML files processed for other web applications deployed on the same Apache Tomcat instance.

All Tomcat users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. Tomcat must be restarted for this update to take effect.


Update the affected tomcat6 packages.
