The version of Firefox ESR installed on the remote Windows host is prior to 78.5. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-51 advisory.

  • Heap buffer overflow in Freetype in Google Chrome prior to 86.0.4240.111 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (CVE-2020-15999)

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