How to fix?

Upgrade freebsd to version 9.3 or higher.

Overview

Affected versions of this package are vulnerable to Information Exposure. The sm_close_on_exec function in conf.c in sendmail before 8.14.9 has arguments in the wrong order, and consequently skips setting expected FD_CLOEXEC flags, which allows local users to access unintended high-numbered file descriptors via a custom mail-delivery program.
