Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

In Apache HTTP server versions 2.4.37 and prior, by sending request bodies in a slow loris way to plain resources, the h2 stream for that request unnecessarily occupied a server thread cleaning up that incoming data. This affects only HTTP/2 (mod_http2) connections.(CVE-2018-17189)

Solution

Run 'yum update mod_http2' to update your system.
