"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by a vulnerability as referenced in the
ALINUX3-SA-2024:0031 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2024-0985:
    Late privilege drop in REFRESH MATERIALIZED VIEW CONCURRENTLY in PostgreSQL allows an object creator to
    execute arbitrary SQL functions as the command issuer. The command intends to run SQL functions as the
    owner of the materialized view, enabling safe refresh of untrusted materialized views. The victim is a
    superuser or member of one of the attacker's roles. The attack requires luring the victim into running
    REFRESH MATERIALIZED VIEW CONCURRENTLY on the attacker's materialized view. As part of exploiting this
    vulnerability, the attacker creates functions that use CREATE RULE to convert the internally-built
    temporary table to a view. Versions before PostgreSQL 15.6, 14.11, 13.14, and 12.18 are affected. The only
    known exploit does not work in PostgreSQL 16 and later. For defense in depth, PostgreSQL 16.2 adds the
    protections that older branches are using to fix their vulnerability.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

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