USN-5487-1 fixed several vulnerabilities in Apache HTTP Server. Unfortunately it caused regressions. USN-5487-2 reverted the patches that caused the regression in Ubuntu 14.04 ESM for further investigation. This update re-adds the security fixes for Ubuntu 14.04 ESM and fixes two different regressions: one affecting modproxy only in Ubuntu 14.04 ESM and another in modsed affecting also Ubuntu 16.04 ESM and Ubuntu 18.04 LTS.
We apologize for the inconvenience.
