summary: Excessive memory growth in net/http and golang.org/x/net/http2
description: |-
    An attacker can cause excessive memory growth in a Go server accepting HTTP/2
    requests.

    HTTP/2 server connections contain a cache of HTTP header keys sent by the
    client. While the total number of entries in this cache is capped, an attacker
    sending very large keys can cause the server to allocate approximately 64 MiB
    per open connection.
