"The version of Microsoft Edge (Chromium) installed on the remote Windows host is prior to 84.0.522.40. It is,
therefore, affected by multiple vulnerabilities :

  - Heap-based buffer overflow in PDFium allowed a remote attacker to potentially exploit heap corruption via a
    crafted PDF file. (CVE-2020-6513)

  - Use after free in tab strip allowed a remote attacker to potentially exploit heap corruption via a crafted
    HTML page. (CVE-2020-6515)

  - Out of bounds write in Skia allowed a remote attacker to potentially exploit heap corruption via a crafted
    HTML page. (CVE-2020-6523)

In addition, Microsoft Edge (Chromium) is also affected by several additional vulnerabilities including additional
use-after-free vulnerabilities, multiple heap-based buffer overflow conditions, privilege escalation, type confusion,
and insufficient policy enforcements.");
