Description

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 :

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.

Upgrade to Microsoft Edge (Chromium) 84.0.522.40 or later.
