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.
