Executive Summaries

The following table summarizes the security bulletins for this month in order of severity.

For details on affected software, see the next section, Affected Software.

Bulletin ID Bulletin Title and Executive Summary Maximum Severity Rating\ and Vulnerability Impact Restart Requirement Known\ Issues Affected Software
MS17-001 Security Update for Microsoft Edge (3214288)\ This security update resolves a vulnerability in Microsoft Edge. This vulnerability could allow an elevation of privilege if a user views a specially crafted webpage using Microsoft Edge. An attacker who successfully exploited this vulnerability could gain elevated permissions on the namespace directory of a vulnerable system and gain elevated privileges Important \ Elevation of Privilege Requires restart --------- Microsoft Windows,\ Microsoft Edge
MS17-002 Security Update for Microsoft Office (3214291)\ This security update resolves a vulnerability in Microsoft Office. The vulnerability could allow remote code execution if a user opens a specially crafted Microsoft Office file. An attacker who successfully exploited the vulnerability 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. Important \ Remote Code Execution May require restart --------- Microsoft Office,\ Microsoft Office Services and Web Apps
MS17-003 Security Update for Adobe Flash Player (3214628)\ This security update resolves vulnerabilities in Adobe Flash Player when installed on all supported editions of Windows 8.1, Windows Server 2012, Windows Server 2012 R2, Windows RT 8.1, Windows 10, and Windows Server 2016. Critical \ Remote Code Execution Requires restart --------- Microsoft Windows,\ Adobe Flash Player
MS17-004 Security Update for Local Security Authority Subsystem Service (3216771)\ A denial of service vulnerability exists in the way the Local Security Authority Subsystem Service (LSASS) handles authentication requests. An attacker who successfully exploited the vulnerability could cause a denial of service on the target system's LSASS service, which triggers an automatic reboot of the system. The security update addresses the vulnerability by changing the way that LSASS handles specially crafted authentication requests. Important \ Denial of Service Requires restart --------- Microsoft Windows

Exploitability Index

The following table provides an exploitability assessment of each of the vulnerabilities addressed this month. The vulnerabilities are listed in order of bulletin ID then CVE ID. Only vulnerabilities that have a severity rating of Critical or Important in the bulletins are included.

How do I use this table?

Use this table to learn about the likelihood of code execution and denial of service exploits within 30 days of security bulletin release, for each of the security updates that you may need to install. Review each of the assessments below, in accordance with your specific configuration, to prioritize your deployment of this month's updates. For more information about what these ratings mean, and how they are determined, please see Microsoft Exploitability Index.

In the columns below, "Latest Software Release" refers to the subject software, and "Older Software Releases" refers to all older, supported releases of the subject software, as listed in the "Affected Software" and "Non-Affected Software" tables in the bulletin.

Affected Software

The following tables list the bulletins in order of major software category and severity.

Use these tables to learn about the security updates that you may need to install. You should review each software program or component listed to see whether any security updates pertain to your installation. If a software program or component is listed, then the severity rating of the software update is also listed.

Note You may have to install several security updates for a single vulnerability. Review the whole column for each bulletin identifier that is listed to verify the updates that you have to install, based on the programs or components that you have installed on your system.

Detection and Deployment Tools and Guidance

Several resources are available to help administrators deploy security updates.

Microsoft Baseline Security Analyzer (MBSA) lets administrators scan local and remote systems for missing security updates and common security misconfigurations.

Windows Server Update Services (WSUS), Systems Management Server (SMS), and System Center Configuration Manager help administrators distribute security updates.

The Update Compatibility Evaluator components included with Application Compatibility Toolkit aid in streamlining the testing and validation of Windows updates against installed applications.

For information about these and other tools that are available, see Security Tools for IT Pros.
