The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2019:0567 advisory.
The OpenStack Load Balancing service (openstack-octavia) provides a Load Balancing-as-a-Service (LBaaS) version 2 implementation for Red Hat OpenStack platform director based installations.
Security Fix(es):
* openstack-octavia: Private keys written to world-readable log files (CVE-2018-16856)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Bug Fix(es):
* This feature is community support and not supported by Red Hat per RHOSP SLA. (BZ#1671022)
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.
