                   Red Hat Security Advisory

Synopsis:          Low: erlang security and bug fix update
Advisory ID:       RHSA-2018:0303-01
Product:           Red Hat Enterprise Linux OpenStack Platform
Advisory URL:      https://access.redhat.com/errata/RHSA-2018:0303
Issue date:        2018-02-13
CVE Names:         CVE-2017-1000385
=====================================================================

1. Summary:

An update for erlang is now available for Red Hat OpenStack Platform 11.0
(Ocata).

Red Hat Product Security has rated this update as having a security impact
of Low. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat OpenStack Platform 11.0 - x86_64

3. Description:

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)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

5. Bugs fixed (https://bugzilla.redhat.com/):

BZ - 1520400 - CVE-2017-1000385 erlang: TLS server vulnerable to Adaptive Chosen 
Ciphertext attack allowing plaintext recovery or MITM attack
BZ - 1536064 - erl_epmd:port_please assumes ipv4
