Allocation of Resources Without Limits or Throttling

CVE-2019-9514

High
7.5/10

Summary

Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of "RST_STREAM" frames from the peer. Depending on how the peer queues the "RST_STREAM" frames, this can consume excess memory, CPU, or both. This issue affects Go-github.com/golang/net, Go-golang.org/x/net versions prior to 0.0.0-20190813141303-74dc4d7220e7, Cpp-h2o versions prior to 2.2.6, Cpp-trafficserver versions 6.0.0 through 6.2.3, 7.0.0 through 7.1.6 and 8.0.0 through 8.0.3 and Maven-io.netty:netty-codec-http2 and Maven-io.netty:netty-all versions prior to 4.1.39.Final.
