"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-2025:0043 advisory.

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

    CVE-2025-0237:
    The WebChannel API, which is used to transport various information across processes, did not check the
    sending principal but rather accepted the principal being sent. This could have led to privilege
    escalation attacks. This vulnerability affects Firefox < 134, Firefox ESR < 128.6, Thunderbird < 134, and
    Thunderbird < 128.6.

    CVE-2025-0238:
    Assuming a controlled failed memory allocation, an attacker could have caused a use-after-free, leading to
    a potentially exploitable crash. This vulnerability affects Firefox < 134, Firefox ESR < 128.6, Firefox
    ESR < 115.19, Thunderbird < 134, and Thunderbird < 128.6.

    CVE-2025-0239:
    When using Alt-Svc, ALPN did not properly validate certificates when the original server is redirecting to
    an insecure site. This vulnerability affects Firefox < 134, Firefox ESR < 128.6, Thunderbird < 134, and
    Thunderbird < 128.6.

    CVE-2025-0240:
    Parsing a JavaScript module as JSON could under some circumstances cause cross-compartment access, which
    may result in a use-after-free. This vulnerability affects Firefox < 134, Firefox ESR < 128.6, Thunderbird
    < 134, and Thunderbird < 128.6.

    CVE-2025-0241:
    When segmenting specially crafted text, segmentation would corrupt memory leading to a potentially
    exploitable crash. This vulnerability affects Firefox < 134, Firefox ESR < 128.6, Thunderbird < 134, and
    Thunderbird < 128.6.

    CVE-2025-0242:
    Memory safety bugs present in Firefox 133, Thunderbird 133, Firefox ESR 115.18, Firefox ESR 128.5,
    Thunderbird 115.18, and Thunderbird 128.5. Some of these bugs showed evidence of memory corruption and we
    presume that with enough effort some of these could have been exploited to run arbitrary code. This
    vulnerability affects Firefox < 134, Firefox ESR < 128.6, Firefox ESR < 115.19, Thunderbird < 134, and
    Thunderbird < 128.6.

    CVE-2025-0243:
    Memory safety bugs present in Firefox 133, Thunderbird 133, Firefox ESR 128.5, and Thunderbird 128.5. Some
    of these bugs showed evidence of memory corruption and we presume that with enough effort some of these
    could have been exploited to run arbitrary code. This vulnerability affects Firefox < 134, Firefox ESR <
    128.6, Thunderbird < 134, and Thunderbird < 128.6.
