Description Pedro Sampaio 2020-06-04 21:18:37 UTC 
Envoy through 1.14.1 may consume excessive amounts of memory when proxying HTTP/2 requests or responses with many small (e.g., 1 byte) data frames.

Comment 3 Mark Cooper 2020-06-30 07:40:58 UTC 
Statement:

A uncontrolled resource consumption vulnerability was found in Envoy. An attacker could craft many HTTP/2 requests (or responses) with very small data frames, to cause the proxy to consume excessive amounts of memory potentially resulting in a denial of service.
