The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:2644 advisory.

- expat: large number of colons in input makes parser consume high amount of resources, leading to DoS (CVE-2018-20843)
