1.15.4 (April 15, 2021)¶
http: fixed a crash upon receiving empty HTTP/2 metadata frames. Received empty metadata frames are now counted in the HTTP/2 codec stat metadata_empty_frames.
http: fixed a remotely exploitable integer overflow via a very large grpc-timeout value causes undefined behavior.
http: fixed URL parsing for HTTP/1.1 fully qualified URLs and connect requests containing IPv6 addresses.
http: fixed bugs in datadog and squash filter’s handling of responses with no bodies.
http: reverting a behavioral change where upstream connect timeouts were temporarily treated differently from other connection failures. The change back to the original behavior can be temporarily reverted by setting envoy.reloadable_features.treat_upstream_connect_timeout_as_connect_failure to false.
tls: fix detection of the upstream connection close event.
Removed Config or Runtime¶
