Apache Tomcat is a servlet container for the Java Servlet and JavaServer
Pages (JSP) technologies.
It was discovered that Apache Tomcat did not limit the length of chunk
sizes when using chunked transfer encoding. A remote attacker could use
this flaw to perform a denial of service attack against Tomcat by streaming
an unlimited quantity of data, leading to excessive consumption of server
It was found that Apache Tomcat did not check for overflowing values when
parsing request content length headers. A remote attacker could use this
flaw to perform an HTTP request smuggling attack on a Tomcat server located
behind a reverse proxy that processed the content length header correctly.
It was found that the org.apache.catalina.servlets.DefaultServlet
implementation in Apache Tomcat allowed the definition of XML External
Entities (XXEs) in provided XSLTs. A malicious application could use this
to circumvent intended security restrictions to disclose sensitive
