"The version of Google Chrome installed on the remote Windows host is prior to 86.0.4240.193. It is, therefore, affected
by a vulnerability as referenced in the 2020_11_stable-channel-update-for-desktop_9 advisory.

  - Inappropriate implementation in base in Google Chrome prior to 86.0.4240.193 allowed a remote attacker who
    had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page.
    (CVE-2020-16016)

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