CVE-2016-0763 (opens in a new tab)How to fix?
Upgrade Debian:8 tomcat7 to version 7.0.56-3+deb8u2 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream tomcat7 package and not the tomcat7 package as distributed by Debian.
See How to fix? for Debian:8 relevant fixed versions and status.
The setGlobalContext method in org/apache/naming/factory/ResourceLinkFactory.java in Apache Tomcat 7.x before 7.0.68, 8.x before 8.0.31, and 9.x before 9.0.0.M3 does not consider whether ResourceLinkFactory.setGlobalContext callers are authorized, which allows remote authenticated users to bypass intended SecurityManager restrictions and read or write to arbitrary application data, or cause a denial of service (application disruption), via a web application that sets a crafted global context.
