The version of Firefox ESR installed on the remote Windows host is prior to 68.4.1. It is, therefore, affected by the vulnerability as referenced in the mfsa2020-03 advisory.

  • Incorrect alias information in IonMonkey JIT compiler for setting array elements could lead to a type confusion. We are aware of targeted attacks in the wild abusing this flaw. (CVE-2019-17026)

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
