"The CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the
TuxCare CENTOS7:CLSA-2026:1787648234 advisory.

  - A vulnerability was found in PostgreSQL. This attack requires permission to create non-temporary objects
    in at least one schema, the ability to lure or wait for an administrator to create or update an affected
    extension in that schema, and the ability to lure or wait for a victim to use the object targeted in
    CREATE OR REPLACE or CREATE IF NOT EXISTS. Given all three prerequisites, this flaw allows an attacker to
    run arbitrary code as the victim role, which may be a superuser. (CVE-2022-2625)

  - Heap buffer overflow in PostgreSQL to_char(timestamptz) allows the party choosing the timezone to execute
    arbitrary code as the operating system user running the database, via a long POSIX timezone abbreviation.
    Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected. (CVE-2026-14669)

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