RHEL 7 : erlang (RHSA-2018:0242)

medium Nessus Plugin ID 210298

Synopsis

The remote Red Hat host is missing a security update for erlang.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2018:0242 advisory.

 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 servers private key itself. (CVE-2017-1000385)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL erlang package based on the guidance in RHSA-2018:0242.
