In Apache MINA, a specifically crafted, malformed HTTP request may cause the HTTP Header decoder to loop indefinitely. The decoder assumed that the HTTP Header begins at the beginning of the buffer and loops if there is more data than expected. Please update MINA to 2.1.5 or greater.
A vulnerability was found in Hibernate-Validator. The SafeHtml validator annotation fails to properly sanitize payloads consisting of potentially malicious code in HTML comments and instructions. This vulnerability can result in an XSS attack.
Apache Tomcat versions 7.0.0 to 7.0.84, 8.0.0.RC1 to 8.0.49 and 8.5.0 to 8.5.27 does not properly handle the URL empty string ("") when used as part of a security constraint definition. This can lead to the security constraint being ignored, leading to unitended exposure of resources.

Apache Tomcat versions 7.0.0 to 7.0.84, 8.0.0.RC1 to 8.0.49 and 8.5.0 to 8.5.27 only apply security constraints defined by Servlets once those Servlets are loaded. Depending on the order that Servlets load, some security constraints may not be applied leading to unintended resource exposure.
