The version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 115.14. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2024-34 advisory.

  - Unexpected marking work at the start of sweeping could have led to a use-after-free. (CVE-2024-7527)

  - 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. (CVE-2024-7519)

  - Incomplete WebAssembly exception handing could have led to a use-after-free. (CVE-2024-7521)

  - Editor code failed to check an attribute value. This could have led to an out-of-bounds read.
    (CVE-2024-7522)

  - 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. (CVE-2024-7524)

The version of firefox installed on the remote host is prior to 115.14.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2FIREFOX-2024-030 advisory.

    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-2024-7519)

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

    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-2024-7522)

    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-2024-7524)

    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-2024-7525)

    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-2024-7526)

    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-2024-7527)

    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-2024-7529)

    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-2024-7531)

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-2024-7531:
    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.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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.
