CVE-2017-1000385

Status Candidate

Overview

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 content or sign messages with the server's private key (this is a variation of the Bleichenbacher attack).

Red Hat Security Advisory 2018-0368-01 - Erlang is a general-purpose programming language and runtime environment. Erlang has built-in support for concurrency, distribution and fault tolerance. Security Fix: An erlang TLS server configured with cipher suites using RSA key exchange, may be vulnerable to an Adaptive Chosen Ciphertext attack against RSA. This may result in plain-text recovery of encrypted messages and/or a man-in-the-middle attack, despite the attacker not having gained access to the serveras private key itself.
