"The version of Microsoft Edge (Chromium) installed on the remote Windows host is prior to 80.0.361.62. It is,
therefore, affected by multiple vulnerabilities:

  - An out-of-bounds memory access error exists in Google Chrome. An unauthenticated, remote attacker can
    exploit this, via a crafted HTML page, to potentially exploit heap corruption. (CVE-2020-6407)

  - A type confusion error exists in the V8 component of Google Chrome. An unauthenticated, remote attacker
    can exploit this, via a crafted HTML page, to potentially exploit heap corruption. (CVE-2020-6418)

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