New! Plugin Severity Now Using CVSS v3

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 80.0.361.48. It is, therefore, affected by multiple vulnerabilities:

- An integer overflow condition exists in the JavaScript component of Google Chrome. An unauthenticated, remote attacker can exploit this, via a crafted HTML page, to potentially exploit heap corruption.
(CVE-2020-6381)

- A type confusion error exists in the JavaScript component of Google Chrome. An unauthenticated, remote attacker can exploit this, via a crafted HTML page, to potentially exploit heap corruption.
(CVE-2020-6382)

- A use-after-free vulnerability exists in the speech component of Google Chrome. An unauthenticated, remote attacker can exploit this, via a crafted HTML page, to potentially exploit heap corruption.
(CVE-2020-6406)

In addition, Microsoft Edge (Chromium) is also affected by several additional vulnerabilities including additional use-after-free vulnerabilities, out-of-bounds read/write, insufficient input validation, and insufficient policy enforcements.

Solution

Upgrade to Microsoft Edge (Chromium) 80.0.361.48 or later.
