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.

Severity Rating: Important

Summary: This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if an authenticated attacker logs on to the target system using RDP and sends specially crafted data over the connection. By default, RDP is not enabled on any Windows operating system. Systems that do not have RDP enabled are not at risk.

Revision Note: V1.0 (February 9, 2016): Bulletin published.
Summary: This security update resolves vulnerabilities in Microsoft Windows. The more severe of the vulnerabilities could allow remote code execution if Microsoft Windows PDF Library improperly handles application programming interface (API) calls, which could allow an attacker to run arbitrary code on the user’s system. 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. However, an attacker would have no way to force users to download or open a malicious PDF document.

Summary: This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if an attacker uses the Microsoft Web Distributed Authoring and Versioning (WebDAV) client to improperly validate input.

Severity Rating: Critical
Revision Note: V1.0 (February 9, 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.

Summary: This security update resolves vulnerabilities in Internet Explorer. The more severe of the vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. 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 control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
