Upgrade Debian:9 postfix to version 2.5.5-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream postfix package and not the postfix package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

Postfix 2.4 before 2.4.9, 2.5 before 2.5.5, and 2.6 before 2.6-20080902, when used with the Linux 2.6 kernel, leaks epoll file descriptors during execution of "non-Postfix" commands, which allows local users to cause a denial of service (application slowdown or exit) via a crafted command, as demonstrated by a command in a .forward file.
