Bugfix (introduced Postfix 2.4): epoll file descriptor leak.
With Postfix >= 2.4 on Linux >= 2.6, Postfix has an epoll
file descriptor leak when it executes non-Postfix commands
in, for example, user-controlled $HOME/.forward files. A
local user can access a leaked epoll file descriptor to
implement a denial of service attack on Postfix. Data
confidentiality and integrity are not affected. File:
util/events.c.
