Description

The HTTP/2 header parser in Apache Tomcat 9.0.0.M1 to 9.0.0.M11 and 8.5.0 to 8.5.6 entered an infinite loop if a header was received that was larger than the available buffer. This made a denial of service attack possible.

• apache tomcat 8.5.0 • apache tomcat 8.5.1 • apache tomcat 8.5.2 • apache tomcat 8.5.3 • apache tomcat 8.5.4 • apache tomcat 8.5.5 • apache tomcat 8.5.6 • apache tomcat 9.0.0
