Improper Access Control
In Apache Tomcat, a malicious web application was able to bypass a configured `SecurityManager` via a Tomcat utility method that was accessible to web applications.
Incorrect Authorization
The ResourceLinkFactory implementation in Apache Tomcat 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to 8.0.36, 7.0.0 to 7.0.70 and 6.0.0 to 6.0.45 does 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.
Denial of Service
The MultipartStream class in this package allows remote attackers to cause a denial of service (CPU consumption) via a long boundary string.
