[1]This update is only available via Windows Update.

[2]Windows 10 updates are cumulative. In addition to containing non-security updates, they also contain all of the security fixes for all of the Windows 10-affected vulnerabilities shipping with the monthly security release. The update is available via the Windows Update Catalog.

[3]Customers running Windows 10 or Windows 10 Version 1511 who have Citrix XenDesktop installed will not be offered the update. Because of a Citrix issue with the XenDesktop software, users who install the update will be prevented from logging on. To stay protected, Microsoft recommends uninstalling the incompatible software and installing this update. Customers should contact Citrix for more information and help with this XenDesktop software issue.

The third-party products that this bulletin discusses are manufactured by companies that are independent of Microsoft. Microsoft makes no warranty, implied or otherwise, about the performance or reliability of these products.

Note Windows Server Technical Preview 3 and Windows Server Technical Preview 4 are affected. Customers running these operating systems are encouraged to apply the update, which is available via Windows Update.

Windows GDI32.dll ASLR Bypass Vulnerability - CVE-2016-0008

A security feature bypass vulnerability exists in the way that the Windows graphics device interface handles objects in memory, allowing an attacker to retrieve information that could lead to an Address Space Layout Randomization (ASLR) bypass.

To exploit this vulnerability, in a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability through Internet Explorer and then convince users to view the website. This could also include compromised websites or websites that accept or host user-provided content or banner advertisements; such websites could contain specially crafted content that is designed to exploit the vulnerability. In all cases, however, an attacker would have no way to force users to visit such websites. Instead, an attacker would have to convince users to do so, typically by getting them to click a link in an email or Instant Messenger request.

In an email attack scenario, an attacker could exploit the vulnerability by sending Outlook users a specially crafted email, or sending them a specially crafted Office document as an attachment, and convincing the user to read the message or open the file.

An attacker could also exploit this vulnerability by hosting a malicious file on a network share and convincing users to navigate to the folder in Windows Explorer. The security update addresses the vulnerability by correcting how the Windows graphics device interface handles memory addresses, thereby helping to protect the integrity of the ASLR security feature.

Microsoft received information about this vulnerability through coordinated vulnerability disclosure. At the time this security bulletin was originally issued, Microsoft was unaware of any attack attempting to exploit this vulnerability.

Win32k Remote Code Execution Vulnerability - CVE-2016-0009

A remote code execution vulnerability exists in the way that Windows handles objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code on a target system.

To exploit this vulnerability, an attacker would first have to convince a user to visit a malicious website that could exploit the vulnerability and run arbitrary code with the logged on user’s privileges. The security update addresses this vulnerability by correcting how Windows handles objects in memory.

This vulnerability has been publicly disclosed. It has been assigned Common Vulnerability and Exposure number CVE-2016-0009. At the time this security bulletin was originally issued, Microsoft was unaware of any attack attempting to exploit this vulnerability.

Mitigating Factors

Microsoft has not identified any mitigating factors for this vulnerability.
