3123479 – Deprecation of SHA-1 Hashing Algorithm for Microsoft Root Certificate Program – Version: 1.0

Revision Note: V1.0 (January 12, 2016): Advisory published.
Summary: Microsoft is announcing a policy change to the Microsoft Root Certificate Program. The new policy no longer allows root certificate authorities to issue X.509 certificates using the SHA-1 hashing algorithm for the purposes of SSL and code signing as of January 1, 2016. Using the SHA-1 hashing algorithm in digital certificates could allow an attacker to spoof content, perform phishing attacks, or perform man-in-the-middle attacks.

MS16-003 – Critical: Cumulative Security Update for JScript and VBScript to Address Remote Code Execution (3125540) – Version: 1.0

Severity Rating: Critical
Revision Note: V1.0 (January 12, 2016): Bulletin published.
Summary: This security update resolves a vulnerability in the VBScript scripting engine in Microsoft Windows. The vulnerability could allow remote code execution if a user visits a specially crafted website. An attacker who successfully exploited this vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

MS16-002 – Critical: Cumulative Security Update for Microsoft Edge (3124904) – Version: 1.0

Severity Rating: Critical
Revision Note: V1.0 (January 12, 2016): Bulletin published.
Summary: This security update resolves vulnerabilities in Microsoft Edge. 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 those who operate with administrative user rights.

MS16-006 – Critical: Security Update for Silverlight to Address Remote Code Execution (3126036) – Version: 1.0

Severity Rating: Critical
Revision Note: V1.0 (January 12, 2016): Bulletin published.
Summary: This security update resolves a vulnerability in Microsoft Silverlight. The vulnerability could allow remote code execution if a user visits a compromised website that contains a specially crafted Silverlight application. An attacker would have no way to force users to visit a compromised website. Instead, an attacker would have to convince users to visit the website, typically by getting them to click a link in an email or instant message that takes users to the attacker’s website.

MS15-126 – Critical: Cumulative Security Update for JScript and VBScript to Address Remote Code Execution (3116178) – Version: 1.0

Severity Rating: Critical
Revision Note: V1.0 (December 8, 2015): Bulletin published.
Summary: This security update resolves vulnerabilities in the VBScript scripting engine in Microsoft Windows. The more severe of the vulnerabilities could allow remote code execution if an attacker hosts a specially crafted website that is designed to exploit the vulnerabilities through Internet Explorer (or leverages a compromised website or a website that accepts or hosts user-provided content or advertisements) and then convinces a user to view the website. An attacker could also embed an ActiveX control marked “safe for initialization” in an application or Microsoft Office document that uses the Internet Explorer rendering engine to direct the user to the specially crafted website.

MS15-131 – Critical: Security Update for Microsoft Office to Address Remote Code Execution (3116111) – Version: 1.0

Severity Rating: Critical
Revision Note: V1.0 (December 8, 2015): Bulletin published.
Summary: This security update resolves vulnerabilities in Microsoft Office. The most severe of the vulnerabilities could allow remote code execution if a user opens a specially crafted Microsoft Office file. An attacker who successfully exploited the vulnerabilities could run arbitrary code in the context of 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.
