The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2023:7714 advisory.

  - IN THE EXTENSION SCRIPT, a SQL Injection vulnerability was found in PostgreSQL if it uses @extowner@,     @extschema@, or @extschema:...@ inside a quoting construct (dollar quoting, '', or ). If an     administrator has installed files of a vulnerable, trusted, non-bundled extension, an attacker with     database-level CREATE privilege can execute arbitrary code as the bootstrap superuser. (CVE-2023-39417)

  - A memory disclosure vulnerability was found in PostgreSQL that allows remote users to access sensitive     information by exploiting certain aggregate function calls with 'unknown'-type arguments. Handling     'unknown'-type values from string literals without type designation can disclose bytes, potentially     revealing notable and confidential information. This issue exists due to excessive data output in     aggregate function calls, enabling remote users to read some portion of system memory. (CVE-2023-5868)

  - A flaw was found in PostgreSQL that allows authenticated database users to execute arbitrary code through     missing overflow checks during SQL array value modification. This issue exists due to an integer overflow     during array modification where a remote user can trigger the overflow by providing specially crafted     data. This enables the execution of arbitrary code on the target system, allowing users to write arbitrary     bytes to memory and extensively read the server's memory. (CVE-2023-5869)

  - A flaw was found in PostgreSQL involving the pg_cancel_backend role that signals background workers,     including the logical replication launcher, autovacuum workers, and the autovacuum launcher. Successful     exploitation requires a non-core extension with a less-resilient background worker and would affect that     specific background worker only. This issue may allow a remote high privileged user to launch a denial of     service (DoS) attack. (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.

The remote Ubuntu 16.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6570-1 advisory.

    Pedro Gallegos discovered that PostgreSQL incorrectly handled modifying certain SQL array values. A remote     attacker could use this issue to obtain sensitive information, or possibly execute arbitrary code.
    (CVE-2023-5869)

    Hemanth Sandrana and Mahendrakar Srinivasarao discovered that PostgreSQL allowed the pg_signal_backend     role to signal certain superuser processes, contrary to expectations. (CVE-2023-5870)

The version of postgresql installed on the remote host is prior to 14.10-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2POSTGRESQL14-2024-004 advisory.

    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)

    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)

    The 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)

The version of postgresql installed on the remote host is prior to 9.2.24-8. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2567 advisory.

    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.

The version of postgresql92 installed on the remote host is prior to 9.2.24-3.70. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2025-1959 advisory.

    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)

    Time-of-check Time-of-use (TOCTOU) race condition in pg_dump in PostgreSQL allows an object creator to     execute arbitrary SQL functions as the user running pg_dump, which is often a superuser. The attack     involves replacing another relation type with a view or foreign table. The attack requires waiting for     pg_dump to start, but winning the race condition is trivial if the attacker retains an open transaction.
    Versions before PostgreSQL 16.4, 15.8, 14.13, 13.16, and 12.20 are affected. (CVE-2024-7348)

      CVE-2023-39418:
      A vulnerability was found in PostgreSQL with the use of the MERGE command, which fails to test new rows     against row security policies defined for UPDATE and SELECT. If UPDATE and SELECT policies forbid some     rows that INSERT policies do not forbid, a user could store such rows.
