| CVE-2019-15541 | Hig | 0.49 | 7.5 | 0.02 | Aug 26, 2019 | rustls-mio/examples/tlsserver.rs in the rustls crate before 0.16.0 for Rust allows attackers to cause a denial of service (loop of conn_event and ready) by arranging for a client to never be writable. | ||
| CVE-2026-93599 | Hig | 0.42 | 7.5 | 0.00 | Sep 18, 2026 | rustls-webpki through 0.103.12 (and 0.104.0-alpha releases before 0.104.0-alpha.7) contains a reachable panic in bit_string_flags() in src/der.rs. The input guard fails to reject a named-bit BIT STRING whose content is exactly [0x00] (zero padding bits and no data bytes), so… | ||
| CVE-2024-32650 | Hig | 0.42 | 7.5 | 0.01 | Apr 19, 2024 | 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… | ||
| CVE-2024-11738 | Med | 0.35 | 5.3 | 0.01 | Dec 6, 2024 | A flaw was found in Rustls 0.23.13 and related APIs. This vulnerability allows denial of service (panic) via a fragmented TLS ClientHello message. | ||

For example, a name constraint of accept.example.com was… | ||
