"The version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 140.1. It is, therefore, affected
by multiple vulnerabilities as referenced in the mfsa2025-59 advisory.

  - Memory safety bugs present in 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-2025-8040)

  - Firefox ignored paths when checking the validity of navigations in a frame. (CVE-2025-8038)

  - 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)

  - Firefox executed <code>javascript:</code> URLs when used in <code>object</code> and <code>embed</code>
    tags. (CVE-2025-8029)

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