This bug was fixed in the package postgresql-12 - 12.8-0ubuntu0.20.04.1
---------------
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:
