This security update resolves vulnerabilities in Microsoft Edge. Microsoft Edge is a web browser included with Windows 10. The most severe of the vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Microsoft Edge. An attacker who successfully exploited these vulnerabilities could gain the same user rights as the current user. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
- Microsoft Windows 10
The security update addresses the vulnerabilities by:
- Modifying how Microsoft edge handles objects in memory
- Helping to ensure that affected versions of Microsoft Edge properly implement the ASLR security feature
These vulnerabilities could allow remote code execution or an elevation of privilege if a user views a specially crafted webpage in Microsoft Edge. An attacker who successfully exploits this vulnerability could gain the same user rights as the current user. Depending on the privileges associated with the user, an attacker could install programs; view, change, or delete data; or create new accounts with full user rights.
- After appropriate testing, apply appropriate patches provided by Microsoft to vulnerable systems.
- Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
- Remind users not to visit untrusted websites or follow links provided by unknown or untrusted sources.
- Do not open email attachments from unknown or untrusted sources or suspicious emails from trusted sources.
