Erlang is a general-purpose programming language and runtime environment. Erlang has built-in support for concurrency, distribution and fault tolerance.

Security Fix(es):

  • 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 having gained access to the server’s private key itself. (CVE-2017-1000385)
