Описание
Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both.
A flaw was found in HTTP/2. Using HEADER frames with invalid HTTP headers and queuing of response RST_STREAM frames, an attacker could cause a flood resulting in unbounded memory growth. The highest threat from this vulnerability is to system availability.
Отчет
The golang package in Red Hat OpenStack Platform 9 Operational Tools will not be updated for this flaw because it is in technical preview and is retiring as of 24.Aug.2019. This issue did not affect the versions of grafana(embeds golang) as shipped with Red Hat Ceph Storage 2 and Red Hat Gluster Storage 3 as they did not include the support for HTTP/2. The following storage product versions are affected because they include the support for HTTP/2 in:
- golang as shipped with Red Hat Gluster Storage 3, Red Hat Ceph Storage 2 and Red Hat Ceph Storage 3
- heketi(embeds golang) as shipped with Red Hat Gluster Storage 3
- grafana(embeds golang and grpc) as shipped with Red Hat Ceph Storage 3 This flaw has no available mitigation for packages golang and nodejs. Both packages will be updated once the available fixes are released for Red Hat Enterprise Linux and Red Hat Software Collections. The nodejs RPM shipped in OpenShift Container Platform 3.9 and 3.10 is not affected by this flaw as it does not contain the vulnerable code. All OpenShift Container Platform RPMs and container images that are built with Go and support HTTP/2 are vulnerable to this flaw.
