Description Carlos López 2024-04-22 11:25:37 UTC

flake-pilot embeds rust-rustls:

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.

Comment 1 Marcus Schäfer 2024-04-22 13:13:00 UTC

Thanks, it seems the mentioned versions are not yet available in the crate index
e.g

failed to select a version for the requirement `rustls = "^0.21.21"`

I guess a little bit of waiting is needed prior the vendor tarball will pick up the fix

Comment 2 Karen Van der Veer 2024-06-06 14:49:01 UTC

Since this is not fixable in the code Marcus wrote, could the security team advise on how to take care of this?

Comment 3 Marcus Schäfer 2024-06-06 14:59:53 UTC

>Since this is not fixable

I rechecked today and the crate index has changed with an update rustls variant.
I will submit a package
