Microsoft Edge (Chromium) < 79.0.309.68 Multiple Vulnerabilities

high Nessus Plugin ID 138175

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

- A spoofing vulnerability exists in the Windows CryptAPI due to how it validates Elliptic Curve Cryptography (ECC) certificates. An unauthenticated, remote attacker can exploit this, by using a spoofed code-signing certificate to sign a malicious executable, to make the executable appear like it is from a trusted, legitimate source. (CVE-2020-0601)

- 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-2020-6378)

- A use-after-free vulnerability 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-2020-6379)

- An insufficient policy enforcement vulnerability exists in Google Chrome. An authenticated, remote attacker that has compromised the renderer process can exploit this, via a crafted Chrome Extension, to bypass site isolation. (CVE-2020-6380)

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) 79.0.309.68 or later.
