This is Kelly Housman with the Microsoft Patch Tuesday newsletter for October 11, 2016.

Do you still have legacy unsupported systems in your environment? Click here to learn how to leverage McAfee solutions to help secure those systems.

 

Welcome to the October Patch Tuesday update. This month was lighter month where Microsoft released a total of Ten (10) new security bulletins, including one for Adobe Flash . For this month, Six (6) of these are rated Critical. These are the types of vulnerabilities that system administrators are usually the most concerned about and attempt to patch as quickly as possible. The remaining Four (4) are rated Important.

 

Clarification of the Intel Security Coverage column in the table below

Some Microsoft bulletins include multiple vulnerabilities. The Covered Products and Under Analysis sections will list Intel Security products for *any* of the vulnerabilities included in the Microsoft bulletin. You may see an Intel Security product listed in both sections, which would indicate that it is Covered for one of the vulnerabilities in the bulletin and Under Analysis for one of the other vulnerabilities. The details for each individual vulnerability are provided in the McAfee Labs Security Advisory Number.

Let’s take a closer look at each of the Microsoft Security Bulletins:

 

MS16-118 (CVE-2016-3267, 3387, 3388, 3384, 3390, 3391, 3298, 3331, 3382, 3383, and 3385 )

This security update resolves vulnerabilities in Internet Explorer. The most 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 the vulnerabilities could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker 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.

This security update is rated Critical for Internet Explorer 9 (IE 9), and Internet Explorer 11 (IE 11) on affected Windows clients, and Moderate for Internet Explorer 9 (IE 9), Internet Explorer 10 (IE 10), and Internet Explorer 11 (IE 11) on affected Windows servers.

The update addresses the vulnerabilities by correcting how Internet Explorer handles:

  • objects in memory
  • namespace boundaries

MS16-119 (CVE-2016-3387, 3388, 3267, 3389, 3390, 3391, 3392, 7194, 3331, 3382, 3386, 7189, and 7190)

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.

This security update is rated Critical for Microsoft Edge on Windows 10.

The update addresses the vulnerabilities by:

  • modifying how Microsoft Edge and certain functions handle objects in memory.
  • modifying how the Chakra JavaScript scripting engine handles objects in memory.
  • restricting what information is returned to Microsoft Edge.
  • changing the way Microsoft Browsers store credentials in memory.
  • correcting how Microsoft Browsers handle namespace boundaries.

correcting how Microsoft Edge Content Security Policy validates documents.

MS16-120 (CVE-2016-3209, 3270, 3396, 7182, 3262, 3263, and 3393)
This security update resolves vulnerabilities in Microsoft Windows, Microsoft Office, Skype for Business, Silverlight and Microsoft Lync. The most serious of these vulnerabilities could allow remote code execution if a user either visits a specially crafted website or opens a specially crafted document.

This security update is rated Critical for:

  • All supported releases of Microsoft Windows
  • Affected editions of Microsoft Office 2007 and Microsoft Office 2010
  • Affected editions of Skype for Business 2016, Microsoft Lync 2013, and Microsoft Lync 2010

This security update is rated Important for:

  • Affected editions of Microsoft .NET Framework
  • Affected editions of Silverlight

The security update addresses the vulnerabilities by correcting how the Windows font library handles embedded fonts.

MS16-121 (CVE-2016-7193 )

An Office RTF remote code execution vulnerability exists in Microsoft Office software when the Office software fails to properly handle RTF files.  An attacker who successfully exploited the vulnerabilities could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

The update addresses the vulnerability by changing the way Microsoft Office software handles RTF content.

MS16-122 (CVE-2016-0142)

The vulnerability could allow remote code execution if Microsoft Video Control fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. However, an attacker must first convince a user to open either a specially crafted file or a program from either a webpage or an email message.

The update addresses the vulnerability by correcting how Microsoft Video Control handles objects in memory.

 

MS16-123 (CVE-2016-3266, 3341, 7211, 7183, 7185, and 3376)

The more severe of the vulnerabilities could allow elevation of privilege if an attacker logs on to an affected system and runs a specially crafted application that could exploit the vulnerabilities and take control of an affected system.

The security update addresses the vulnerabilities by correcting how the Windows kernel-mode driver handles objects in memory.

 

MS16-124 (CVE-2016-0070, 0073, 0075, and 0079)

The vulnerabilities could allow elevation of privilege if an attacker can access sensitive registry information.

The security update addresses the vulnerabilities by correcting how the kernel API restricts access to this information.

MS16-125 (CVE-2016-7188)
The vulnerability could allow elevation of privilege if an attacker logs on to an affected system and runs a specially crafted application.

The security update addresses the vulnerability by correcting how the Windows Diagnostics Hub Standard Collector Service sanitizes input, to help preclude unintended elevated system privileges.

 

MS16-126 (CVE-2016-0026, 3332, 3333, 3334, 3335, 3338, 3340, 3342, 3343, and 7184)

The vulnerability could allow elevation of privilege when the Windows Common Log File System (CLFS) driver improperly handles objects in memory. In a local attack scenario, an attacker could exploit these vulnerabilities by running a specially crafted application to take complete control over the affected system. An attacker who successfully exploits this vulnerability could run processes in an elevated context.

The update addresses the vulnerabilities by correcting how CLFS handles objects in memory.

 

MS16-127 (N/A)

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, and Windows 10.

This security update is rated Critical. The update addresses the vulnerabilities in Adobe Flash Player by updating the affected Adobe Flash libraries contained within Internet Explorer 10, Internet Explorer 11, and Microsoft Edge.

 

 

NOTE: A bit of clarification might be in order here. Readers may wonder why we don’t often mention McAfee VirusScan or other technologies as mitigations for these vulnerabilities. The industry generally describes a security vulnerability as an unintentional coding or design flaw in software that may leave it potentially open to exploitation. While there may be some forms of defense against any given vulnerability being exploited, in some cases the only way to truly mitigate the issue is to patch the vulnerable software. Since our focus here is on Microsoft Security Bulletins, it might be useful to read the Microsoft Security Response Center’s definition of a security vulnerability.

 

Memory Corruption Vulnerabilities:

Intel Security is seeing many Memory Corruption Remote Code Execution vulnerabilities that affect a large number of products…not just those from Microsoft. This is an area where customers can see immediate value when using McAfee Host Intrusion Prevention. For example, by enabling protection and applying the Default IPS (Intrusion Prevention System) Rules policy, we have demonstrated that 90 percent or more of the Microsoft vulnerabilities listed in Patch Tuesday updates were shielded using this out-of-the-box basic protection level.

 

 

Further research is being performed 24/7 by McAfee Labs, and coverage may improve as additional results come in.  As more details become available, you’ll find them on the McAfee Threat Center.  You might also be interested in subscribing to McAfee Labs Security Advisories, where you can get real-time updates via email.
