HTTP/2: large amount of data requests leads to denial of service

A flaw was found in HTTP/2. An attacker can request a large amount of data by manipulating window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this queue can consume excess CPU, memory, or both, leading to a...

The vulnerability of the HTTP2 Stream Handler component in the Apache Tomcat application server allows a attacker to cause a service failure.
