  script_tag(name:"insight", value:"This update for proftpd fixes the following issues:

  * GeoIP has been discontinued by Maxmind (boo#1156210) This update removes
  module build for geoip.

  - CVE-2019-19269: Fixed a NULL pointer dereference may occur when
  validating the certificate of a client connecting to the server
  (boo#1157803)

  - CVE-2019-19270: Fixed a Failure to check for the appropriate field of a
  CRL entry prevents some valid CRLs from being taken into account
  (boo#1157798)

  - CVE-2019-18217: Fixed remote unauthenticated denial-of-service due to
  incorrect handling of overly long commands (boo#1154600 gh#846)

  Update to 1.3.6b

  * Fixed pre-authentication remote denial-of-service issue (Issue #846).

  * Backported fix for building mod_sql_mysql using MySQL 8 (Issue #824).

  Update to 1.3.6a:

  * Fixed symlink navigation (Bug#4332).

  * Fixed building of mod_sftp using OpenSSL 1.1.x releases (Issue#674).

  * Fixed SITE COPY honoring of <Limit> restrictions (Bug#4372).

  * Fixed segfault on login when using mod_sftp + mod_sftp_pam (Issue#656).

  * Fixed restarts when using mod_facl as a static module

  * Add missing Requires(pre): group(ftp) for Leap 15 and Tumbleweed
  (boo#1155834)

  * Add missing Requires(pre): user(ftp) for Leap 15 and Tumbleweed
  (boo#1155834)

  * Use pam_keyinit.so (boo#1144056)

  - Reduce hard dependency on systemd to only that which is necessary for
  building and installation.

  update to 1.3.6:

  * Support for using Redis for caching, logging, see the
  doc/howto/Redis.html documentation.

  * Fixed mod_sql_postgres SSL support (Issue #415).

  * Support building against LibreSSL instead of OpenSSL (Issue #361).

  * Better support on AIX for login restraictions (Bug #4285).

  * TimeoutLogin (and other timeouts) were not working properly for SFTP
  connections (Bug#4299).

  * Handling of the SIGILL and SIGINT signals, by the daemon process, now
  causes the child processes to be terminated as well (Issue #461).

  * RPM .spec file naming changed to conform to Fedora guidelines.

  * Fix for 'AllowChrootSymlinks off' checking each component for symlinks
  (CVE-2017-7418).

  New Modules:

  * mod_redis, mod_tls_redis, mod_wrap2_redis With Redis now supported as a
  caching mechanism, similar to Memcache, there are now Redis-using
  modules: mod_redis (for configuring the Redis connection information),
  mod_tls_redis (for caching SSL sessions and OCSP information using
  Redis), and mod_wrap2_redis ..
