An important Exim security release

There are, it seems, 21 vulnerabilities in the
Exim email server that have been fixed in the 4.94.2 release; at least some
of these are remotely exploitable for root access.
'The current Exim versions (and likely older versions too) suffer from
several exploitable vulnerabilities. These vulnerabilities were reported
by Qualys via security@exim.org back in October 2020.

Due to several internal reasons it took more time than usual for the Exim
development team to work on these reported issues in a timely
manner.' See this advisory
from Qualys for the details.
