Microsoft Edge (Chromium) < 80.0.361.62 Multiple Vulnerabilities

high Nessus Plugin ID 138176
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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

- An out-of-bounds memory access error exists in Google Chrome. An unauthenticated, remote attacker can exploit this, via a crafted HTML page, to potentially exploit heap corruption. (CVE-2020-6407)

- A type confusion error exists in the V8 component of Google Chrome. An unauthenticated, remote attacker can exploit this, via a crafted HTML page, to potentially exploit heap corruption. (CVE-2020-6418)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Microsoft Edge (Chromium) 80.0.361.62 or later.
