Excessive Iteration

CVE-2021-39204

High
7.5/10

Summary

Pomerium is an open source identity-aware access proxy. Envoy, which Pomerium is based on, incorrectly handles resetting of HTTP/2 streams with excessive complexity. This can lead to high CPU utilization when a large number of streams are reset. This can result in a DoS condition. Pomerium versions prior to 0.14.8 and 0.15.x prior to 0.15.1 contain an upgraded envoy binary with this vulnerability patched.
