"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-2024:0402 advisory.

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

    CVE-2024-7518:
    Select options could obscure the fullscreen notification dialog. This could be used by a malicious site to
    perform a spoofing attack. This vulnerability affects Firefox < 129, Firefox ESR < 128.1, and Thunderbird
    < 128.1.

    CVE-2024-7519:
    Insufficient checks when processing graphics shared memory could have led to memory corruption. This could
    be leveraged by an attacker to perform a sandbox escape. This vulnerability affects Firefox < 129, Firefox
    ESR < 115.14, Firefox ESR < 128.1, Thunderbird < 128.1, and Thunderbird < 115.14.

    CVE-2024-7520:
    A type confusion bug in WebAssembly could be leveraged by an attacker to potentially achieve code
    execution. This vulnerability affects Firefox < 129, Firefox ESR < 128.1, and Thunderbird < 128.1.

    CVE-2024-7521:
    Incomplete WebAssembly exception handing could have led to a use-after-free. This vulnerability affects
    Firefox < 129, Firefox ESR < 115.14, Firefox ESR < 128.1, Thunderbird < 128.1, and Thunderbird < 115.14.

    CVE-2024-7522:
    Editor code failed to check an attribute value. This could have led to an out-of-bounds read. This
    vulnerability affects Firefox < 129, Firefox ESR < 115.14, Firefox ESR < 128.1, Thunderbird < 128.1, and
    Thunderbird < 115.14.

    CVE-2024-7524:
    Firefox adds web-compatibility shims in place of some tracking scripts blocked by Enhanced Tracking
    Protection.  On a site protected by Content Security Policy in strict-dynamic mode, an attacker able to
    inject an HTML element could have used a DOM Clobbering attack on some of the shims and achieved XSS,
    bypassing the CSP strict-dynamic protection. This vulnerability affects Firefox < 129, Firefox ESR <
    115.14, and Firefox ESR < 128.1.

    CVE-2024-7525:
    It was possible for a web extension with minimal permissions to create a StreamFilter which could be used
    to read and modify the response body of requests on any site. This vulnerability affects Firefox < 129,
    Firefox ESR < 115.14, Firefox ESR < 128.1, Thunderbird < 128.1, and Thunderbird < 115.14.

    CVE-2024-7526:
    ANGLE failed to initialize parameters which led to reading from uninitialized memory. This could be
    leveraged to leak sensitive data from memory. This vulnerability affects Firefox < 129, Firefox ESR <
    115.14, Firefox ESR < 128.1, Thunderbird < 128.1, and Thunderbird < 115.14.

    CVE-2024-7527:
    Unexpected marking work at the start of sweeping could have led to a use-after-free. This vulnerability
    affects Firefox < 129, Firefox ESR < 115.14, Firefox ESR < 128.1, Thunderbird < 128.1, and Thunderbird <
    115.14.

    CVE-2024-7528:
    Incorrect garbage collection interaction in IndexedDB could have led to a use-after-free. This
    vulnerability affects Firefox < 129, Firefox ESR < 128.1, and Thunderbird < 128.1.

    CVE-2024-7529:
    The date picker could partially obscure security prompts. This could be used by a malicious site to trick
    a user into granting permissions. This vulnerability affects Firefox < 129, Firefox ESR < 115.14, Firefox
    ESR < 128.1, Thunderbird < 128.1, and Thunderbird < 115.14.
