Description Martin Prpič 2016-11-01 04:58:29 EDT 
The following flaw was reported in Tomcat:

The ResourceLinkFactory did not limit web application access to global JNDI resources to those resources explicitly linked to the web application. Therefore, it was possible for a web application to access any global JNDI resource whether an explicit ResourceLink had been configured or not.
