Описание
github.com/kumahq/kuma affected by CVE-2023-44487
Impact
Envoy and Go HTTP/2 protocol stack is vulnerable to the "Rapid Reset" class of exploits, which send a sequence of HEADERS frames optionally followed by RST_STREAM frames.
This can be exercised if you use the builtin gateway and receive untrusted http2 traffic.
Patches
https://github.com/kumahq/kuma/pull/8023 https://github.com/kumahq/kuma/pull/8001 https://github.com/kumahq/kuma/pull/8034
Workarounds
Disable http2 on the gateway listener with a MeshProxyPatch or ProxyTemplate.
