Red Hat Security Advisory 2018-0303-01
Posted Feb 13, 2018
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2018-0303-01 - 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.
