Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
This security update resolves vulnerabilities in Microsoft Windows. The most severe of these vulnerabilities could allow elevation of privilege if an attacker logs on to the system and runs a specially crafted application. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
This security update is rated Important for all supported releases of Windows. For more information, see the Affected Software section.
The security update addresses the vulnerabilities by correcting how the Windows kernel-mode driver handles objects in memory and validates user input. For more information about the vulnerabilities, see the Vulnerability Information section.
For more information about this update, see Microsoft Knowledge Base Article 3057839 .
Note The update is available for Windows Technical Preview and Windows Server Technical Preview. Customers running these operating systems are encouraged to apply the update, which is available via Windows Update.
[1] This update is available via Windows Update only.
*The Updates Replaced column shows only the latest update in a chain of superseded updates. For a comprehensive list of updates replaced, go to the Microsoft Update Catalog, search for the update KB number, and then view update details (updates replaced information is on the Package Details tab).
The following severity ratings assume the potential maximum impact of the vulnerability. For information regarding the likelihood, within 30 days of this security bulletin's release, of the exploitability of the vulnerability in relation to its severity rating and security impact, please see the Exploitability Index in the June bulletin summary .
An information disclosure vulnerability exists when the Windows kernel-mode driver improperly handles buffer elements under certain conditions, allowing an attacker to request the contents of specific memory addresses. An attacker who successfully exploited this vulnerability could then potentially read data that is not intended to be disclosed. This vulnerability would not allow an attacker to execute code or to elevate their user rights directly, but it could be used to obtain information in an attempt to further compromise the affected system. Workstations and servers are primarily at risk. Servers could be at more risk if administrators allow users to log on to servers and to run programs. However, best practices strongly discourage this.
To exploit this vulnerability an attacker must have valid logon credentials and be able to execute programs on the system. The security update addresses the vulnerability by correcting how the Windows kernel-mode driver validates memory addresses.
Microsoft received information about this vulnerability through coordinated vulnerability disclosure. When this security bulletin was originally issued Microsoft had not received any information to indicate that this vulnerability had been publicly used to attack customers.
The following mitigating factors may be helpful in your situation:
Microsoft has not identified any workarounds for this vulnerability.
An elevation of privilege vulnerability exists when the Windows kernel-mode driver improperly frees an object in memory that an attacker could use to execute arbitrary code with elevated permissions. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full administrative rights.
To exploit this vulnerability an attacker would first have to log on to the system or convince a logged-on user to execute a specially crafted application. Workstations and terminal servers are primarily at risk. The update addresses the vulnerability by changing how certain objects are handled in memory.

The following mitigating factors may be helpful in your situation:
Microsoft has not identified any workarounds for this vulnerability.
An elevation of privilege vulnerability exists in the Windows kernel-mode driver due to insufficient validation of certain data passed from user mode. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application designed to increase privileges. The update addresses the vulnerability by ensuring that the kernel-mode driver properly validates data passed from user mode.

The following workarounds may be helpful in your situation:
Disable NULL page mapping on Windows 7
Note This workaround only applies to Windows 7.
Click Start , click Run , in the Open box type regedit , and then click OK .
Locate and then click the following registry subkey:
On the Edit menu, point to New , and then click DWORD .
Type EnableLowVaAccess , and then press Enter.
On the Edit menu, click Modify to modify the EnableLowAvAccess registry entry.
In the Valuedata box, type 0 , and then click OK .
Impact of workaround. A restart is required. Some 16-bit applications may not work as expected.
Click Start , click Run , in the Open box type regedit , and then click OK .
Locate and then click the following registry subkey:
On the Edit menu, click Delete on the EnableLowAvAccess registry entry.
Multiple elevation of privilege vulnerabilities exist in the Windows kernel-mode driver when it accesses an object in memory that has either not been correctly initialized or deleted. The vulnerabilities may corrupt memory in such a way that an attacker could gain elevated privileges on a targeted system.
An authenticated attacker who successfully exploited these vulnerabilities could acquire elevated privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full administrative rights.
To exploit the vulnerabilities, an attacker would first have to log on to the system. An attacker could then run a specially crafted application designed to increase privileges. The update addresses the vulnerabilities by correcting how the kernel-mode driver handles objects in memory.

An elevation of privilege vulnerability exists when the Windows kernel-mode driver, Win32k.sys , fails to properly free memory. An attacker who successfully exploited this vulnerability could execute arbitrary code within the context of another user. If that other user has elevated rights, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

We have a web service referencing a dll, having winform, with Panel having controls (Label, Pictureboxs etc.). In code we call Panel.DrawToBitmap() method to draw image. This is working fine for more than 4 years. But after installing windows update KB
3057839 . Panel.DrawToBitmap() method is returning an blank image. After removing update it starts working fine. We can't ask with client to remove Window update on the server. Please have alook into this issue. Thanks.
