  openvpn (2.4.12-0ubuntu0.20.04.1) focal; urgency=medium

  * New upstream releases 2.4.8-2.4.12 (LP: #2004676)
    - The version is being updated to the latest in 2.4.x rather than 2.6.x to
      avoid feature releases and focus on bug fixes
    - Updates:
      + Support compiling with OpenSSL 1.1 without deprecated APIs
      + Handle PSS padding in cryptoapicert (necessary for TLS >= 1.2)
      + Client will now announce the acceptable ciphers to the server
        (IV_CIPHER=...), so NCP cipher negotiation works better

      + CVE-2020-11810
      + CVE-2020-15078
      + CVE-2022-0547

      + Fix argv leaks in add_route() and add_route_ipv6()
      + Ensure the current common_name is in the environment for scripts
      + Apply connect-retry backoff only to one side of the connection for p2p
      + Fix PIN querying in systemd environments
      + Fix condition where a client's session could float to a new IP address
        that is not authorized
      + Fix combination of async push and NCP
      + Fix OpenSSL error stack handling of tls_ctx_add_extra_certs
      + Fix broken fragmentation logic when using NCP
      + Fix handling of 'route remote_host' for IPv6 transport case
