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)

Important: Exim now cleans the complete execution environment by default. This affects Exim and subprocesses such as transports calling other programs. The following new options are supported to adjust this behaviour:

• keep_environment
• add_environment A warning will be printed upon startup if none of these are configured.

Also includes upstream changes, improvements and bug fixes:

• Support for using the system standard CA bundle.
• New expansion items $config_file, $config_dir, containing the file and directory name of the main configuration file. Also $exim_version.
• New 'malware=' support for Avast.
• New 'spam=' variant option for Rspamd.
• 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 {}} expansion.
• A non-SMTP authenticator using information from TLS client certificates.
• Main option 'tls_eccurve' for selecting an Elliptic Curve for TLS.
• Main option 'dns_trust_aa' for trusting your local nameserver at the same level as DNSSEC.
