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

- Heap-based buffer overflow in PDFium allowed a remote attacker to potentially exploit heap corruption via a crafted PDF file. (CVE-2020-6513)

- Out of bounds write in Skia allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (CVE-2020-6523)

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.

Solution

Upgrade to Microsoft Edge (Chromium) 84.0.522.40 or later.
