"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-2026:0404 advisory.

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

    CVE-2026-8631:
    A potential security vulnerability has been identified in the HP Linux Imaging and Printing Software. This
    potential vulnerability may allow escalation of privileges and/or arbitrary code execution via operating
    system command injection.

    CVE-2026-8632:
    A potential security vulnerability has been identified in the HP Linux Imaging and Printing Software. This
    potential vulnerability may allow escalation of privileges and/or arbitrary code execution via an integer
    overflow in the hpcups processing path when handling crafted print data.

    CVE-2025-43023:
    A potential security vulnerability has been identified in the HP Linux Imaging and Printing Software
    documentation. This potential vulnerability is due to the use of a weak code signing key, Digital
    Signature Algorithm (DSA).

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

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