Summary: This security update resolves vulnerabilities in Microsoft Edge. The most severe of the vulnerabilities could allow information disclosure 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.
