"The version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 115.26. It is, therefore, affected
by multiple vulnerabilities as referenced in the mfsa2025-57 advisory.

  - Memory safety bugs present in Firefox ESR 115.25, Firefox ESR 128.12, Thunderbird ESR 128.12, Firefox ESR
    140.0, Thunderbird ESR 140.0, 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-2025-8034)

  - 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)

  - 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)

  - The JavaScript engine did not handle closed generators correctly and it was possible to resume them
    leading to a nullptr deref. (CVE-2025-8033)

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