Description

This update to exim 4.86.2 fixes the following issues :

 - CVE-2016-1531: local privilege escalation for set-uid root exim when using 'perl_startup' (boo#968844)

 - Assorted options on malware= and spam= scanners.

 - A commandline option to write a comment into the logfile.

 - A logging option for slow DNS lookups.

 - New $(env (<variable>)) expansion.

 - Main option 'tls_eccurve' for selecting an Elliptic Curve for TLS.
