SUSE CVE-2026-55953

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 downgrade...

SUSE CVE-2026-42790

Improper Certificate Validation vulnerability in Erlang OTP publickey pubkeycert and publickey modules allows a DNS nameConstraints bypass via subject CommonName fallback in TLS hostname verification. Two flaws combine to allow a subordinate CA whose DNS nameConstraints are restricted e.g...

MiracleLinux 7 : erlang-18.3.4.7-1.0.1.el7.AXS7 (AXSA:2017-2480:01)

The remote MiracleLinux 7 host has a package installed that is affected by a vulnerability as referenced in the AXSA:2017-2480:01 advisory. The Erlang otp TLS server answers with different TLS alerts to different error types in the RSA PKCS 1 1.5 padding. This allows an attacker to decrypt conten...

erlang: TLS server vulnerable to Adaptive Chosen Ciphertext attack allowing plaintext recovery or MITM attack

An erlang TLS server configured with cipher suites using RSA key exchange, may be vulnerable to an Adaptive Chosen Ciphertext attack AKA Bleichenbacher attack against RSA. This may result in plain-text recovery of encrypted messages and/or a man-in-the-middle MiTM attack, despite the attacker not...
