"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-2025:0151 advisory.

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

    CVE-2025-1017:
    Memory safety bugs present in Firefox 134, Thunderbird 134, Firefox ESR 128.6, and Thunderbird 128.6. 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 < 135, Firefox ESR <
    128.7, Thunderbird < 128.7, and Thunderbird < 135.

    CVE-2025-1016:
    Memory safety bugs present in Firefox 134, Thunderbird 134, Firefox ESR 115.19, Firefox ESR 128.6,
    Thunderbird 115.19, and Thunderbird 128.6. 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 < 135, Firefox ESR < 115.20, Firefox ESR < 128.7, Thunderbird < 128.7, and
    Thunderbird < 135.

    CVE-2025-1014:
    Certificate length was not properly checked when added to a certificate store. In practice only trusted
    data was processed. This vulnerability affects Firefox < 135, Firefox ESR < 128.7, Thunderbird < 128.7,
    and Thunderbird < 135.

    CVE-2025-1013:
    A race condition could have led to private browsing tabs being opened in normal browsing windows. This
    could have resulted in a potential privacy leak. This vulnerability affects Firefox < 135, Firefox ESR <
    128.7, Thunderbird < 128.7, and Thunderbird < 135.

    CVE-2025-1012:
    A race during concurrent delazification could have led to a use-after-free. This vulnerability affects
    Firefox < 135, Firefox ESR < 115.20, Firefox ESR < 128.7, Thunderbird < 128.7, and Thunderbird < 135.

    CVE-2025-1011:
    A bug in WebAssembly code generation could have lead to a crash. It may have been possible for an attacker
    to leverage this to achieve code execution. This vulnerability affects Firefox < 135, Firefox ESR < 128.7,
    Thunderbird < 128.7, and Thunderbird < 135.

    CVE-2025-1010:
    An attacker could have caused a use-after-free via the Custom Highlight API, leading to a potentially
    exploitable crash. This vulnerability affects Firefox < 135, Firefox ESR < 115.20, Firefox ESR < 128.7,
    Thunderbird < 128.7, and Thunderbird < 135.

    CVE-2025-1009:
    An attacker could have caused a use-after-free via crafted XSLT data, leading to a potentially exploitable
    crash. This vulnerability affects Firefox < 135, Firefox ESR < 115.20, Firefox ESR < 128.7, Thunderbird <
    128.7, and Thunderbird < 135.
