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.

Un atacante puede provocar un crecimiento excesivo de la memoria en un servidor Go que acepta solicitudes HTTP/2. Las conexiones del servidor HTTP/2 contienen un caché de claves de encabezado HTTP enviadas por el cliente. Si bien el número total de entradas en esta caché está limitado, un atacante que envía claves muy grandes puede hacer que el servidor asigne aproximadamente 64 MiB por conexión abierta.
