Synopsis

The remote host has an web browser installed that is affected by multiple vulnerabilities.

Description

The version of Microsoft Edge (Chromium) installed on the remote Windows host is prior to 83.0.478.37. It is, therefore, affected by multiple vulnerabilities:

- A use after free in media in Microsoft Edge (Chromium) allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page.
(CVE-2020-6466)

- A use after free in WebRTC in Microsoft Edge (Chromium) allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (CVE-2020-6467)

- Type confusion in V8 in Microsoft Edge (Chromium) allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (CVE-2020-6468)

In addition, Microsoft Edge (Chromium) is also affected by several additional vulnerabilities including additional use-after-free vulnerabilities, privilege escalations, and insufficient policy enforcements.

Solution

Upgrade to Microsoft Edge (Chromium) 83.0.478.37 or later.
