Description Carlos López 2024-04-22 11:21:16 UTC 
atuin 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 Filippo Bonazzi 2024-04-22 11:49:56 UTC 
We are embedding affected version 0.21.10 in our vendored dependencies archive at the moment:

```Cargo.lock
[[package]]
name = "rustls"
version = "0.21.10"
source = "registry+https://github.com/rust-lang/crates.io-index"
checksum = "f9d5a6813c0759e4609cd494e8e725babae6a2ca7b62a5536a13daaec6fcb7ba"
...
```

I will revendor and submit to Factory.
Comment 2 Filippo Bonazzi 2024-04-22 12:12:48 UTC 
That doesn't work as the vulnerable rustls versions is locked in the upstream atuin tarball Cargo.lock / Cargo.toml.

Upstream already contains a fix for this in git (https://github.com/atuinsh/atuin/commit/9ee1fb809f2a83bd8b039143e5013fa89a0784bc). So either we apply this patch or we wait for a fixed upstream release.

@uncomfyhalomacro can you do this?
