MS16-052 – Critical: Cumulative Security Update for Microsoft Edge (3155538) – Version: 1.0 Severity Rating: CriticalRevision Note: V1.0 (May 10, 2016): Bulletin published.Summary: This security update resolves vulnerabilities in Microsoft Edge. 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 the 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 users with administrative user rights.

3155527 – Update to Cipher Suites for FalseStart – Version: 1.0 Revision Note: V1.0 (May 10, 2016): Advisory published.Summary: FalseStart allows the TLS client to send application data before receiving and verifying the server Finished message. This allows an attacker to launch a man-in-the-middle (MiTM) attack to force the TLS client to encrypt the first flight of application_data records using the attacker’s chosen cipher suite from the client’s list. To avoid downgrade attacks, TLS clients only allow FalseStart when their strongest cipher suites are negotiated. Source: 3155527 – Update to Cipher Suites for FalseStart – Version: 1.0

MS16-066 – Important: Security Update for Virtual Secure Mode (3155451) – Version: 1.0 Severity Rating: ImportantRevision Note: V1.0 (May 10, 2016): Bulletin published. Summary: This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow security feature bypass if an attacker runs a specially crafted application to bypass code integrity protections in Windows.
