"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-2025:0961 advisory.

    CVE-2025-14333:
    Memory safety bugs present in Firefox ESR 140.5, Thunderbird ESR 140.5, Firefox 145 and Thunderbird 145.
    Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of

    Firefox ESR < 140.6.

    CVE-2025-14329:
    Privilege escalation in the Netmonitor component. This vulnerability affects Firefox < 146 and Firefox ESR
    < 140.6.

    CVE-2025-14328:
    Privilege escalation in the Netmonitor component. This vulnerability affects Firefox < 146 and Firefox ESR
    < 140.6.

    CVE-2025-14325:
    JIT miscompilation in the JavaScript Engine: JIT component. This vulnerability affects Firefox < 146 and
    Firefox ESR < 140.6.

    CVE-2025-14324:
    JIT miscompilation in the JavaScript Engine: JIT component. This vulnerability affects Firefox < 146,
    Firefox ESR < 115.31, and Firefox ESR < 140.6.
