How to fix?

Upgrade RHEL:7 tomcat-jsvc to version 0:7.0.54-8.el7_2 or higher.
This issue was patched in RHSA-2016:2046.

NVD Description

Note: Versions mentioned in the description apply only to the upstream tomcat-jsvc package and not the tomcat-jsvc package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The Expression Language (EL) implementation in Apache Tomcat 6.x before 6.0.44, 7.x before 7.0.58, and 8.x before 8.0.16 does not properly consider the possibility of an accessible interface implemented by an inaccessible class, which allows attackers to bypass a SecurityManager protection mechanism via a web application that leverages use of incorrect privileges during EL evaluation.
