The version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 78.1. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-32 advisory.

  • Inappropriate implementation in WebRTC in Google Chrome prior to 84.0.4147.89 allowed an attacker in a privileged network position to potentially exploit heap corruption via a crafted SCTP stream. (CVE-2020-6514)

  • Use after free in ANGLE in Google Chrome prior to 81.0.4044.122 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.
    (CVE-2020-6463)

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