"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-2024:0472 advisory.

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

    CVE-2024-8381:
    Firefox normally asks for confirmation before asking the operating system to find an application to handle
    a scheme that the browser does not support. It did not ask before doing so for the Usenet-related schemes
    news: and snews:. Since most operating systems don't have a trusted newsreader installed by default, an
    unscrupulous program that the user downloaded could register itself as a handler. The website that served
    the application download could then launch that application at will. This vulnerability affects Firefox <
    130, Firefox ESR < 128.2, and Firefox ESR < 115.15.

    CVE-2024-8382:
    Internal browser event interfaces were exposed to web content when privileged EventHandler listener
    callbacks ran for those events. Web content that tried to use those interfaces would not be able to use
    them with elevated privileges, but their presence would indicate certain browser features had been used,
    such as when a user opened the Dev Tools console. This vulnerability affects Firefox < 130, Firefox ESR <
    128.2, and Firefox ESR < 115.15.

    CVE-2024-8383:
    A potentially exploitable type confusion could be triggered when looking up a property name on an object
    being used as the `with` environment. This vulnerability affects Firefox < 130, Firefox ESR < 128.2, and
    Firefox ESR < 115.15.

    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-2024-7521:
    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-2024-7529:
    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.

    CVE-2024-8384:
    The JavaScript garbage collector could mis-color cross-compartment objects if OOM conditions were detected
    at the right point between two passes. This could have led to memory corruption. This vulnerability
    affects Firefox < 130, Firefox ESR < 128.2, and Firefox ESR < 115.15.

    CVE-2024-7531:
    Calling `PK11_Encrypt()` in NSS using CKM_CHACHA20 and the same buffer for input and output can result in
    plaintext on an Intel Sandy Bridge processor. In Firefox this only affects the QUIC header protection
    feature when the connection is using the ChaCha20-Poly1305 cipher suite. The most likely outcome is
    connection failure, but if the connection persists despite the high packet loss it could be possible for a
    network observer to identify packets as coming from the same source despite a network path change. This
    vulnerability affects Firefox < 129, Firefox ESR < 115.14, and Firefox ESR < 128.1.

    CVE-2024-7652:
    An error in the ECMA-262 specification relating to Async Generators could have resulted in a type
    confusion, potentially leading to memory corruption and an exploitable crash. This vulnerability affects
    Firefox < 128, Firefox ESR < 115.13, Thunderbird < 115.13, and Thunderbird < 128.
