Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 61d74f80-5e9e-11f0-8baa-8447094a420f advisory.

The mod_http2 project reports:
a client can increase memory consumption for a HTTP/2 connection via repeated request header names,leading to denial of service certain proxy configurations whith mod_proxy_http2 as the backend, an assertion can be triggered by certain requests, leading to denial of service

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

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

Solution

Update the affected packages.
