net/http: excessive memory growth in a Go server accepting HTTP/2 requests
CVE: CVE-2022-41717
Component: golang
CWE: CWE-770
Severity: Moderate
CVSS v3: 5.3/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L
Release date: 2022-11-30T00:00:00+00:00

A flaw was found in the net/http library of the golang package. This flaw allows an attacker to 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.

Statement: Within Red Hat OpenShift Container Platform, the grafana container is listed as will not fix. Since OCP 4.10, Grafana itself is not shipped and the Grafana web server is protected behind an OAuth proxy server.
