"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)
