Description

The version of Microsoft Edge (Chromium) installed on the remote Windows host is prior to 80.0.361.69. It is, therefore, affected by multiple vulnerabilities:

  • A use-after-free error exists in the WebGL component of Microsoft Edge (Chromium). An unauthenticated, remote attacker can exploit this, via a crafted HTML page, to potentially exploit heap corruption. (CVE-2020-6422)

  • A use-after-free error exists in the media component of Microsoft Edge (Chromium). An unauthenticated, remote attacker can exploit this, via a crafted HTML page, to potentially exploit heap corruption. (CVE-2020-6424)

  • A use-after-free error exists in the audio component of Microsoft Edge (Chromium). An unauthenticated, remote attacker can exploit this, via a crafted HTML page, to potentially exploit heap corruption. (CVE-2020-6427)

In addition, Microsoft Edge (Chromium) is also affected by several additional vulnerabilities and errors including additional use-after-free vulnerabilities, an out-of-bounds read, and an insufficient policy enforcement. Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
