Security Bulletin:SSL/TLS Client Cipher Suite Selection Flaw Allows On-Path Attackers to Bypass Certificate Verification

Summary The Erlang/OTP ssl TLS 1.2 and earlier and DTLS client does not verify that the cipher suite selected by the server in ServerHello was among the suites offered by the client in ClientHello. The client-side tlshandshake:hello/5 handler validates the negotiated protocol version and the...

GHSA-2MJX-QC3C-RQVC Rustls: TLS 1.3 handshake messages incorrectly accepted across encryption level boundaries

Rustls accepted TLS 1.3 handshake messages sent at the wrong encryption level when they followed a key-changing message in the same record. The handshake transcript is still authenticated, so a network-position attacker cannot use this to alter or complete a handshake; the practical effect is tha...
