Source Advisory Statement

During startup, an attacker that can man-in-the-middle traffic to and from NTS key exchange servers can trigger a very expensive key validation process due to a vulnerability in webpki. ### Impact This vulnerability can lead to excessive cpu usage on startup on clients configured to use NTS ### Patches Affected users are recommended to upgrade to version 0.3.7 ### References See also https://github.com/rustsec/advisory-db/blob/main/crates/rustls-webpki/RUSTSEC-2023-0053.md
