  script_tag(name:"insight", value:"This update for stunnel fixes the following issues:
  Update to 5.62 including new features and bugfixes:

  * Security bugfixes

  - The 'redirect' option was fixed to properly handle unauthenticated
           requests (bsc#1182529).

  - Fixed a double free with OpenSSL older than 1.1.0.

  - Added hardening to systemd service (bsc#1181400).

  * New features

  - Added new 'protocol = capwin' and 'protocol = capwinctrl'
           configuration file options.

  - Added support for the new SSL_set_options() values.

  - Added a bash completion script.

  - New 'sessionResume' service-level option to allow or disallow
           session resumption

  - Download fresh ca-certs.pem for each new release.

  - New 'protocolHeader' service-level option to insert custom 'connect'
           protocol negotiation headers. This feature can be used to
           impersonate other software (e.g. web browsers).

  - 'protocolHost' can also be used to control the client SMTP protocol
           negotiation HELO/EHLO value.

  - Initial FIPS 3.0 support.

  - Client-side 'protocol = ldap' support

  * Bugfixes

  - Fixed a transfer() loop bug.

  - Fixed reloading configuration with 'systemctl reload
           stunnel.service'.

  - Fixed incorrect messages logged for OpenSSL errors.

  - Fixed 'redirect' with 'protocol'.  This combination is not supported
           by 'smtp', 'pop3' and 'imap' protocols.

  - X.509v3 extensions required by modern versions of OpenSSL are added
           to generated self-signed test certificates.

  - Fixed a tiny memory leak in configuration file reload error handling.

  - Fixed engine initialization.

  - FIPS TLS feature is reported when a provider or container is
           available, and not when FIPS control API is available.

  - Fix configuration reload when compression is used

  - Fix test suite fixed not to require external connectivity");
