SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated tomcat packages that fix one security issue are now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having Low 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.
Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies.
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 a backported patch to correct this issue. Tomcat must be restarted for this update to take effect.
SolutionUpdate the affected packages.
