Synopsis

The remote FreeBSD host is missing a security-related update.

Description

Qualys reports :

We discovered a minor vulnerability in OpenSMTPD, OpenBSD's mail server : an unprivileged local attacker can read the first line of an arbitrary file (for example, root's password hash in /etc/master.passwd) or the entire contents of another user's file (if this file and /var/spool/smtpd/ are on the same filesystem).

Solution

Update the affected package.
