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

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

According to its self-reported version, the Tenable Security Center running on the remote host is between 6.6.0 and 6.8.0. It is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2026-19 advisory.

  - Tenable Security Center is affected by a SQL injection vulnerability. (CVE-2026-64877)

  - Double Free and possible RCE vulnerability in Apache HTTP Server with the HTTP/2 protocol. This issue     affects Apache HTTP Server: 2.4.66. Users are recommended to upgrade to version 2.4.67, which fixes the     issue. (CVE-2026-23918)

  - Stack buffer overflow in PostgreSQL module refint allows an unprivileged database user to execute     arbitrary code as the operating system user running the database. A distinct attack is possible if the     application declares a user-controlled column as a refint cascade primary key and facilitates user-     controlled updates to that column. In that case, a SQL injection allows a primary key update value     provider to execute arbitrary SQL as the database user performing the primary key update. Versions before     PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected. (CVE-2026-6637)

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

The remote Debian 13 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6270 advisory.

    Multiple security issues were discovered in PostgreSQL, which may result     in authorisation bypass, execution of arbitrary code, information     disclosure, privilege escalation, SQL injection or denial of service.

    For the stable distribution (trixie), these problems have been fixed in     version 17.10-0+deb13u1.

    We recommend that you upgrade your postgresql-17 packages.

    For the detailed security status of postgresql-17 please refer to     its security tracker page at:
    https://security-tracker.debian.org/tracker/postgresql-17

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2026:0343 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2026-6637:
    Stack buffer overflow in PostgreSQL module refint allows an unprivileged database user to execute     arbitrary code as the operating system user running the database.  A distinct attack is possible if the     application declares a user-controlled column as a refint cascade primary key and facilitates user-     controlled updates to that column.  In that case, a SQL injection allows a primary key update value     provider to execute arbitrary SQL as the database user performing the primary key update.  Versions before     PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.

    CVE-2026-6477:
    Use of inherently dangerous function PQfn(..., result_is_int=0, ...) in PostgreSQL libpq lo_export(),     lo_read(), lo_lseek64(), and lo_tell64() functions allows the server superuser to overwrite a client stack     buffer with an arbitrarily-large response.  Like gets(), PQfn(..., result_is_int=0, ...) stores arbitrary-     length, server-determined data into a buffer of unspecified size.  Because both the \lo_export command in     psql and pg_dump call lo_read(), the server superuser can overwrite pg_dump or psql stack memory.
    Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.

    CVE-2026-6475:
    Symlink following in PostgreSQL pg_basebackup plain format and in pg_rewind allows an origin superuser to     overwrite local files, e.g. /var/lib/postgres/.bashrc, that hijack the operating system account.  It will     remain the case that starting the server after these commands implicitly trusts the origin superuser, due     to features like shared_preload_libraries.  Hence, the attack has practical implications only if one takes     relevant action between these commands and server start, like moving the files to a different VM or     snapshotting the VM.  Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.

    CVE-2026-6473:
    Integer wraparound in multiple PostgreSQL server features allows an unprivileged database user to cause     the server to undersize an allocation and write out-of-bounds.  This may execute arbitrary code as the     operating system user running the database.  In applications that pass gigabyte-scale user inputs to the     relevant database functions, the application input provider may achieve a segmentation fault.  Versions     before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.

    CVE-2026-6472:
    Missing authorization in PostgreSQL CREATE TYPE allows an object creator to hijack other queries that use     search_path to find user-defined types, including extension-defined types.  That is to say, the victim     will execute arbitrary SQL functions of the attacker's choice.  Versions before PostgreSQL 18.4, 17.10,     16.14, 15.18, and 14.23 are affected.

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2026:0650 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

    CVE-2026-6473:
    Integer wraparound in multiple PostgreSQL server features allows an unprivileged database user to cause     the server to undersize an allocation and write out-of-bounds.

    CVE-2026-6478:
    Covert timing channel in comparison of MD5-hashed password in PostgreSQL authentication allows an attacker     to recover user credentials sufficient to authenticate.  This does not affect scram-sha-256 passwords, the     default in all supported releases.  However, current databases may have MD5-hashed passwords originating     in upgrades from PostgreSQL 13 or earlier.  Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and     14.23 are affected.
