  script_tag(name:"insight", value:"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 { variable }} 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.");
