Description SMASH SMASH 2023-09-26 08:35:39 UTC

this also affects nghttp2

Envoy is a cloud-native high-performance edge/middle/service proxy. Envoy’s
HTTP/2 codec may leak a header map and bookkeeping structures upon receiving
`RST_STREAM` immediately followed by the `GOAWAY` frames from an upstream
server. In nghttp2, cleanup of pending requests due to receipt of the `GOAWAY`
frame skips de-allocation of the bookkeeping structure and pending compressed
header. The error return [code path] is taken if connection is already marked
for not sending more requests due to `GOAWAY` frame. The clean-up code is right
after the return statement, causing memory leak. Denial of service through
memory exhaustion. This vulnerability was patched in versions(s) 1.26.3, 1.25.8,
1.24.9, 1.23.11.
