"It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-1313 advisory.

    Missing authorization in PostgreSQL CREATE STATISTICS command allows a table owner to achieve denial of
    service against other CREATE STATISTICS users by creating in any schema.  A later CREATE STATISTICS for
    the same name, from a user having the CREATE privilege, would then fail.  Versions before PostgreSQL 18.1,
    17.7, 16.11, 15.15, 14.20, and 13.23 are affected. (CVE-2025-12817)

    Integer wraparound in multiple PostgreSQL libpq client library functions allows an application input
    provider or network peer to cause libpq to undersize an allocation and write out-of-bounds by hundreds of
    megabytes.  This results in a segmentation fault for the application using libpq.  Versions before
    PostgreSQL 18.1, 17.7, 16.11, 15.15, 14.20, and 13.23 are affected. (CVE-2025-12818)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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