Red Hat OpenStack 9.0 RHSA-2018:0528-01 Low: TLS Man-in-the-Middle Risk

Calendar Grey March 15, 2018
Scroller Redhat
A Python patch with Minor vulnerability risk for Fedora Cloud Image delivers essential corrections for possible exploits.
An update for erlang is now available for Red Hat OpenStack Platform 9.0 (Mitaka)

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

Summary

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)
