CVE-2016-0763 (opens in a new tab)How to fix?
Upgrade Amazon-Linux:2018.03 tomcat7-lib to version 0:7.0.68-1.15.amzn1 or higher.
This issue was patched in ALAS-2016-680.
NVD Description
Note: Versions mentioned in the description apply only to the upstream tomcat7-lib package and not the tomcat7-lib package as distributed by Amazon-Linux.
See How to fix? for Amazon-Linux:2018.03 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.
