"The version of Google Chrome installed on the remote Windows host is prior to 83.0.4103.88. It is, therefore, affected
by multiple vulnerabilities as referenced in the 2020_06_stable-channel-update-for-desktop advisory.

  - Use after free in payments in Google Chrome on MacOS prior to 83.0.4103.97 allowed a remote attacker to
    potentially perform a sandbox escape via a crafted HTML page. (CVE-2020-6496)

  - Use after free in WebAuthentication in Google Chrome prior to 83.0.4103.97 allowed a remote attacker who

  - Incorrect security UI in payments in Google Chrome on Android prior to 83.0.4103.97 allowed a remote
    attacker to spoof the contents of the Omnibox (URL bar) via a crafted HTML page. (CVE-2020-6494)

  - Insufficient policy enforcement in developer tools in Google Chrome prior to 83.0.4103.97 allowed an
    attacker who convinced a user to install a malicious extension to potentially perform a sandbox escape via
    a crafted Chrome Extension. (CVE-2020-6495)

  - Insufficient policy enforcement in Omnibox in Google Chrome on iOS prior to 83.0.4103.88 allowed a remote
    attacker to perform domain spoofing via a crafted URI. (CVE-2020-6497)

number.");
