Use after free in WebAudio in Google Chrome prior to 80.0.3987.162 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.

The version of Microsoft Edge (Chromium) installed on the remote Windows host is prior to 80.0.361.109. It is, therefore, affected by multiple vulnerabilities:

  - A use-after-free error exists in the WebAudio component of Google Chrome. An unauthenticated, remote attacker     can exploit this, via a crafted HTML page, to potentially exploit heap corruption. (CVE-2020-6450, CVE-2020-6451)

  - A heap-based buffer overflow condition exists Google Chrome. An unauthenticated, remote attacker     can exploit this, via a crafted HTML page, to potentially exploit heap corruption. (CVE-2020-6452)

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