✅ Remediation

Before applying this update, make sure all previously released errata relevant to your system have been applied. For details on how to apply this update, refer to: https://access.redhat.com/articles/11258 Workaround: Users are strongly urged to update their software as soon as fixes are available. There are several mitigation approaches for this flaw. 1. If circumstances permit, users may disable http2 endpoints to circumvent the flaw altogether until a fix is available. 2. IP-based blocking or flood protection and rate control tools may be used at network endpoints to filter incoming traffic. 3. Several package specific mitigations are also available. a. nginx: https://www.nginx.com/blog/http-2-rapid-reset-attack-impacting-f5-nginx-products/ b. netty: https://github.com/netty/netty/security/advisories/GHSA-xpw8-rcwv-8f8p c. haproxy: https://www.haproxy.com/blog/haproxy-is-not-affected-by-the-http-2-rapid-reset-attack-cve-2023-44487 d. nghttp2: https://github.com/nghttp2/nghttp2/security/advisories/GHSA-vx74-f528-fxqg e. golang: The default stream concurrency limit in golang is 250 streams (requests) per HTTP/2 connection. This value may be adjusted in the golang.org/x/net/http2 package using the Server.MaxConcurrentStreams setting and the ConfigureServer function which are available in golang.org/x/net/http2.
