Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The Exim development team reports :

All installations having Exim set-uid root and using 'perl_startup' are vulnerable to a local privilege escalation. Any user who can start an instance of Exim (and this is normally any user) can gain root privileges. If you do not use 'perl_startup' you should be safe.

Solution

Update the affected packages.
