Target Milestone: ---
Classification: Other
A flaw was found in the Apache Tomcat, where an h2c direct connection did not
release the HTTP/1.1 processor after the upgrade to HTTP/2. If a sufficient
number of such requests were made, an OutOfMemoryException could occur leading
to a denial of service.
It affects the version of Apache Tomcat 10.0.0-M1 to 10.0.0-M6, Apache Tomcat
9.0.0.M5 to 9.0.36, Apache Tomcat 8.5.1 to 8.5.56.
