[Marc Deslauriers]

postgresql-12 (12.8-0ubuntu0.20.04.1) focal-security; urgency=medium

  * New upstream version (LP: #1939396).

    + Disallow SSL renegotiation more completely (Michael Paquier)

      SSL renegotiation has been disabled for some time, but the server
      would still cooperate with a client-initiated renegotiation request.
      A maliciously crafted renegotiation request could result in a server
      crash (see OpenSSL issue CVE-2021-3449).  Disable the feature
      altogether on OpenSSL versions that permit doing so, which are
      1.1.0h and newer.
      (CVE-2021-3449)

    + Details about these and many further changes can be found at:
