medium Nessus Plugin ID 165163

Language:

Synopsis

The remote Red Hat host is missing a security update for Red Hat OpenStack Platform 16.1 (openstack-neutron).

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2021:3481 advisory.

 Neutron is a virtual network service for Openstack, and a part of Netstack.
 Just like OpenStack Nova provides an API to dynamically request and configure virtual servers, Neutron provides an API to dynamically request and configure virtual networks. These networks connect interfaces from other OpenStack services (e.g., virtual NICs from Nova VMs). The Neutron API supports extensions to provide advanced network capabilities (e.g., QoS, ACLs, network, monitoring, etc.)

 Security Fix(es):

 * arbitrary dnsmasq reconfiguration via extra_dhcp_opts (CVE-2021-40085)

 For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page listed in the References section.

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 Red Hat OpenStack Platform 16.1 (openstack-neutron) package based on the guidance in RHSA-2021:3481.
