"The version of Firefox installed on the remote macOS or Mac OS X host is prior to 141.0. It is, therefore, affected by
multiple vulnerabilities as referenced in the mfsa2025-56 advisory.

  - Memory safety bugs present in Firefox 140 and Thunderbird 140. 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. (CVE-2025-8044)

  - On 64-bit platforms IonMonkey-JIT only wrote 32 bits of the 64-bit return value space on the stack.
    Baseline-JIT, however, read the entire 64 bits. (CVE-2025-8027)

  - On arm64, a WASM <code>brtable</code> instruction with a lot of entries could lead to the label being too
    far from the instruction causing truncation and incorrect computation of the branch address.
    (CVE-2025-8028)

  - In the address bar, Firefox for Android truncated the display of URLs from the end instead of prioritizing
    the origin. (CVE-2025-8041)

  - Firefox for Android allowed a sandboxed iframe without the <code>allow-downloads</code> attribute to start
    downloads. (CVE-2025-8042)

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