The issue is due to the fact that the\nAuthoritative Server will exit when it tries to store the notified serial in\nthe PostgreSQL database, if this serial cannot be represented in 31 bits\n(CVE-2019-10203).\n\nAn issue has been found in PowerDNS Authoritative Server before 4.3.1 where an\nauthorized user with the ability to insert crafted records into a zone might be\nable to leak the content of uninitialized memory. Such a user could be a\ncustomer inserting data via a control panel, or somebody with access to the\nREST API.
