Summary

The remote host is missing an update for the 'tomcat' package(s) announced via the referenced advisory.

Insight

Insight

Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies. The following packages have been upgraded to a later upstream version: tomcat (7.0.76). (BZ#1414895) Security Fix(es): * The Realm implementations did not process the supplied password if the supplied user name did not exist. This made a timing attack possible to determine valid user names. Note that the default configuration includes the LockOutRealm which makes exploitation of this vulnerability harder. (CVE-2016-0762) * It was discovered that a malicious web application could bypass a configured SecurityManager via a Tomcat utility method that was accessible to web applications. (CVE-2016-5018) * It was discovered that when a SecurityManager was configured, Tomcat's system property replacement feature for configuration files could be used by a malicious web application to bypass the SecurityManager and read system properties that should not be visible. (CVE-2016-6794) * It was discovered that a malicious web application could bypass a configured SecurityManager via manipulation of the configuration parameters for the JSP Servlet. (CVE-2016-6796) * It was discovered that it was possible for a web application to access any global JNDI resource whether an explicit ResourceLink had been configured or not. (CVE-2016-6797) Additional Changes: For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.4 Release Notes linked from the References section.
