Description of the Security and Quality Rollup for .NET Framework 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1, and 4.7.2 for Windows 7 SP1 and Server 2008 R2 SP1, and for .NET Framework 4.6 for Server 2008 SP2 (KB 4344146)

Description

None ## Summary This security update resolves an information disclosure vulnerability in Microsoft .NET Framework that could allow an attacker to access information in multi-tenant environments. The vulnerability is caused when .NET Framework is used in high-load/high-density network connections in which content from one stream can blend into another stream.To exploit the vulnerability, an attacker who can access one tenant in a high-load/high-density environment could potentially trigger multi-tenanted data exposure from one customer to another.This security update addresses the vulnerability by correcting the way that .NET Framework handles high-load/high-density network connections.To learn more about this vulnerability, see [Microsoft Common Vulnerabilities and Exposures CVE-2018-8360](<https://portal.msrc.microsoft.com/security-guidance/advisory/CVE-2018-8360>).**Important** * All updates for .NET Framework 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1, and 4.7.2 require the d3dcompiler_47.dll update to be installed. We recommend that you install the included d3dcompiler_47.dll update before you apply this update. For more information about the d3dcompiler_47.dll update, see [KB 4019990](<https://support.microsoft.com/en-us/help/4019990>) for Windows 7 SP1 and Windows Server 2008 R2 SP1. Or, see [KB 4019478](<https://support.microsoft.com/en-us/help/4019478>) for Windows Server 2008 SP2. * If you install a language pack after you install this update, you must reinstall this update. Therefore, we recommend that you install any language packs that you need before you install this update. For more information, see [Add language packs to Windows](<https://technet.microsoft.com/en-us/library/hh825699>). ## Additional information about this security update For more information about this security update as it relates to Windows 7 Service Pack 1 (SP1) and Windows Server 2008 R2 SP1, see the following article in the Microsoft Knowledge Base:[4345590](<https://support.microsoft.com/help/4345590>) Security and Quality Rollup updates for .NET Framework 3.5.1, 4.5.2, 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1, and 4.7.2 for Windows 7 SP1 and Server 2008 R2 SP1 (KB 4345590)For more information about this security update as it relates to Windows Server 2008, see the following article in the Microsoft Knowledge Base:[4345593](<https://support.microsoft.com/help/4345593>) Security and Quality updates for .NET Framework 2.0 SP2, 3.0 SP2, 4.5.2, and 4.6 for Windows Server 2008 SP2 (KB 4345593) ## How to obtain and install the update ### Method 1: Windows Update This update is available through Windows Update.
