Rustls is a modern TLS library written in Rust.
rustls::ConnectionCommon::complete_io
could fall into an infinite loop
based on network input. When using a blocking rustls server, if a client
send a close_notify
message immediately after client_hello
, the
server’s complete_io
will get in an infinite loop. This vulnerability is
fixed in 0.23.5, 0.22.4, and 0.21.11.
