Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-4113-2 advisory.

 USN-4113-1 fixed vulnerabilities in the Apache HTTP server. Unfortunately, that update introduced a regression when proxying balancer manager connections in some configurations. This update fixes the problem.

 We apologize for the inconvenience.
