"text": "Red Hat rates the security impact of this vulnerability as Important due to the worst case scenario resulting in a denial of service. It is simple to exploit, could significantly impact availability, and there is not a suitable mitigation for all use cases. Once an attack has ended, the system should return to normal operations on its own.\n\nThis vulnerability only impacts servers which have HTTP/2 enabled. It stems from an imperfect definition of the protocol. As the Go programming language is widely utilized across nearly every major Red Hat offering, a full listing of impacted packages will not be provided. Therefore, the \u201cAffected Packages and Issued Red Hat Security Errata\u201d section contains a simplified list of what offerings need to remediate this vulnerability. Every impacted offering has at least one representative component listed, but potentially not all of them. Rest assured that Red Hat is committed to remediating this vulnerability across our entire portfolio.\n\nMany components are rated as Low impact due to configurations which reduce the attack surface or significantly increase the difficulty of exploitation. A summary of these scenarios are:\n* The container includes a package that provides a vulnerable webserver, but it is not used or running during operation\n* HTTP/2 is disabled by default and is not supported\n* Only a client implementation is provided, which is not vulnerable\n* A vulnerable module (either golang.org/net/http or golang.org/x/net/http2) is included, but disabled\n* Access to a vulnerable server is restricted within the container (loopback only connections)\n* Golang is available in the container but is not used\n\n\nWithin the Red Hat OpenShift Container Platform, the majority of vulnerable components are not externally accessible. This means an attacker must already have access to a container within your environment to exploit this vulnerability. However, the ose-hyperkube (openshift-enterprise-hyperkube) container is externally accessible, so there are less barriers to exploitation. Fixes for this specific container are already available.\n\nWithin Red Hat Ansible Automation Platform, the impacted component is Receptor. The impact has been reduced to Low as the vulnerable code is present, but not utilized. There are three potential exposures within this component:\n* Receptor utilizes QUIC a UDP based protocol which does not run over HTTP/2\n* Receptor utilizes the x/net/ipv4 and ipv6 packages, both of which are not affected",
