The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3651 advisory.

  - PostgreSQL Project reports:              Certain aggregate function calls receiving unknown-type     arguments could disclose bytes of server memory from the end of             the unknown-type value to     the next zero byte. One typically             gets an unknown-type value via a string literal having no     type             designation. We have not confirmed or ruled out viability of             attacks that     arrange for presence of notable, confidential             information in disclosed bytes.
    (CVE-2023-5868)

  - PostgreSQL Project reports:              While modifying certain SQL array values, missing     overflow checks let authenticated database users write             arbitrary bytes to a memory area that     facilitates             arbitrary code execution. Missing overflow checks also             let     authenticated database users read a wide area of             server memory. The CVE-2021-32027 fix covered     some             attacks of this description, but it missed others.            (CVE-2023-5869)

  - PostgreSQL Project reports:              Documentation says the pg_cancel_backend role cannot     signal a backend owned by a superuser. On the             contrary, it can signal background workers,     including             the logical replication launcher. It can signal             autovacuum workers and     the autovacuum launcher.             Signaling autovacuum workers and those two launchers     provides no meaningful exploit, so exploiting this             vulnerability requires a non-core extension     with a             less-resilient background worker. For example, a             non-core background worker     that does not auto-restart             would experience a denial of service with respect to     that particular background worker.            (CVE-2023-5870)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
