Solution Customers are advised to follow KB for instructions pertaining to the remediation of these vulnerabilities. Patches: The following are links for downloading patches to fix these vulnerabilities: KB An elevation of privilege vulnerability exists when the Windows kernel fails to properly handle objects in memory.
An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. NET Core installations on the remote host contain vulnerable packages. NET Core, remove vulnerable packages and refer to vendor advisory. These were removed due to Access Denied errors which have been resolved in later cumulative patches. An attacker who successfully exploited the vulnerability could cause a system to stop responding. Note that the denial of service condition would not allow an attacker to execute code or to elevate user privileges.
However, the denial of service condition could prevent authorized users from using system resources. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user.
An attacker who successfully exploited the vulnerability could cause a target system to stop responding. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker who successfully exploited the vulnerability could force the browser to load data that would otherwise be restricted. An attacker who successfully exploited the vulnerability could bypass content blocking. In a file- sharing attack scenario, an attacker could provide a specially crafted document file designed to exploit the vulnerability, and then convince a user to open the document file.
The security update addresses the vulnerability by correcting how Microsoft WordPad handles input. NET Framework which could allow an attacker to elevate their privilege level. An attacker who successfully exploited the vulnerability could impersonate processes, interject cross-process communication, or interrupt system functionality.
An attacker who successfully exploited this vulnerability could take control of an affected system. An attacker who successfully exploited the vulnerability could use the sandbox escape to elevate privileges on an affected system. This vulnerability by itself does not allow arbitrary code execution.
However, the vulnerability could allow arbitrary code to run if an attacker uses it in combination with another vulnerability, such as a remote code execution vulnerability or another elevation of privilege vulnerability, that can leverage the elevated privileges when code execution is attempted. The security update addresses the vulnerability by correcting how Windows file picker handles paths. NET Framework components do not correctly validate certificates.
An attacker could present expired certificates when challenged. The security update addresses the vulnerability by ensuring that. NET Framework components correctly validate certificates. An attacker who successfully exploited this vulnerability could inject code into a trusted PowerShell process to bypass the Device Guard Code Integrity policy on the local machine.
An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. By itself, the CFG bypass vulnerability does not allow arbitrary code execution. However, an attacker could use the CFG bypass vulnerability in conjunction with another vulnerability, such as a remote code execution vulnerability, to run arbitrary code on a target system.
An attacker who successfully exploited this vulnerability could trick a user into believing that the user was on a legitimate website. The specially crafted website could either spoof content or serve as a pivot to chain an attack with other vulnerabilities in web services. This is for Visual Studio Update 5. This is for Visual Studio Update 3. The files are stored on security-enhanced servers that help prevent any unauthorized changes to the files. The dates and times for these files on your local computer are displayed in your local time and with your current daylight saving time DST bias.
Additionally, the dates and times may change when you perform certain operations on the files. But remember that the baseline is just that: a starting point. If monitoring security events works better for you than monitoring firewall logs, do so. Or if you want to use both, do so.
Windows 10 v RS4 has greatly expanded its manageability using Mobile Device Management MDM. We will publish the baseline in MDM form as soon as it is ready. Web 應用程序越來越成為諸如跨站點腳本、SQL 注入和應用程序 DDoS 等攻擊的目標。儘管OWASP 提供了編寫應用程序的指導，使其能夠更好地抵禦此類攻擊，但它需要在多層應用程序拓撲中進行嚴格的維護和修補。 Microsoft Web 應用程序防火牆（WAF） 和 Azure 安全中心（ASC） 可幫助保護 Web 應用程序免受此類漏洞的攻擊。. Microsoft WAF 是 Azure 應用程序網關 （第 7 層負載均衡器）的一項功能，可使用 OWASP 核心規則集 保護 Web 應用程序免受常見 Web 漏洞攻擊。 Azure 安全中心會針對漏洞掃描 Azure 資源，並針對這些問題推薦緩解措施。一個這樣的漏洞是存在不受 WAF 保護的 Web 應用程序。目前，Azure 安全中心建議對面向公眾的 IP 進行 WAF 部署，這些 IP 具有關聯的網絡安全組並具有開放的入站 Web 端口（80和）。 Azure 安全中心 提供應用程序網關 WAF 到現有 Azure 資源的供應，並向現有 Web 應用程序防火牆添加新資源。通過與 WAF 集成，Azure 安全中心可以分析其日誌並顯示重要的安全警報。.
在某些情況下，安全管理員可能沒有資源權限從 Azure 安全中心提供 WAF，或者應用程序所有者已將 WAF 配置為應用程序部署的一部分。為了適應這些情況，我們很高興地宣布，安全中心很快會自動發現預訂中未使用安全中心進行配置的 WAF 實例。以前供應的 WAF 實例將顯示在安全管理中心可以將其與 Azure 安全中心集成的已發現解決方案下的安全中心安全解決方案窗格中。連接現有的微軟 WAF 部署將允許客戶利用安全中心檢測的優勢，而不管 WAF 是如何配置的。其他配置設置（如自定義防火牆規則集）可在直接從安全中心鏈接的 WAF 控制台中使用。這篇關於 配置 Microsoft WAF 的文章可以提供關於配置過程的更多指導。.

In today’s blog post we are going to see about Unity3d – Using LUIS for voice activated commands by Chilberto. This article explains about how to call Language Understanding Intelligent Service LUIS from Unity3d. The reason why I have selected this article is as this article talks about Unity3d with the combination of Language Understanding Intelligent Service LUIS.
There are very articles which explains about Unity3d and this article is special as this article also describing about how to call the LUIS from Unity3d. Language Understanding LUIS allows your application to understand what a person wants in their own words.
LUIS uses machine learning to allow developers to build applications that can receive user input in natural language and extract meaning from it. Chilberto also explained in this article as this post is continues of his previous post Azure Cognitive Services – Bing Speech API and Language Understanding Intelligent Service LUIS and in that article he has explained about using Azure Cognitive Services using LUIS with Speech API.
The example shown here is simple and, in all likelihood, controlling the movement of a ship would be easier to be done with an arrow or WASD keys. But imagine a more complex scenario. For example, Lock phasers on target alpha, strength to stun or All ahead full to Alpha Centauri in the Gamma Quadrant. It is a guess that many players of loot grabbing games on consoles would have loved a voice-controlled inventory system: Sell to a merchant, all ammo where the inventory is over 10 and not used by any of my guns.
I believe this article will be a great feast for all who is looking to work with Unity3d and Cognitive Services ,don’t miss to read this article from here Unity3d – Using LUIS for voice activated commands by Chilberto. I hope you all enjoy reading his article. Yours, Syed Shanu MSDN Profile MVP Profile Facebook Twitter TechNet Wiki the community where we all join hands to share Microsoft-related information. Beginning June , in SharePoint Online, Microsoft will remove the in-product UI entry point for automatic translations.
The configuration options during variation use will be removed and hardcoded to false. The APIs will be marked as deprecated with limited support, but will continue to remain available if users want to integrate directly via custom code.
Microsoft recommends that users leverage the Bing translation APIs directly. However, users will still be able to continue accessing the existing APIs via custom code, but support is limited. Please see this document for more information about SharePoint Machine Translation Variations. For SharePoint on-premise, Microsoft we will not remove the UX entry points or API, but will communicate that this feature is deprecated.
Beginning in June , the UI entry point to SiteManager. aspx will be removed from SharePoint Online and direct access will be restricted to Site Collection Admins.
The main functionality of Site Manager has been implemented in modern file move and copy. For more information about how to move and copy files in a document library in SharePoint, see the following Microsoft websites:. Mikrosegmentace per VM? Nebo pravidla na subnet? In the past, Hello hybrid scenario users had to wait thirty minutes after first creating a PIN before they could use it to logon due to the time it takes for a public key to sync back to the on-premises AD using AAD Connect.
If the user tried to logon before the sync-back they might see the following error message:. Recent improvements to the Hybrid Certificate Trust scenario reduces the wait time for public key sync-back from the original thirty minutes to one minute or less, making it almost instantaneous by comparison. Users can now use their certificate with PIN or biometrics for authentication almost immediately resulting in a vastly improved experience. NOTE: This does not change or affect hybrid key-trust deployments.
Users in these deployments must still wait for the public key to sync to on-premises Active Directory before they can authenticate with their PIN or biometric.

Each year, the Microsoft Cloud and Hosting Summit provides an unparalleled opportunity for leaders across the industry to connect and share ideas on how to expand and build new services, drive innovation, and create new business opportunities.
This year we are pleased to provide you the ability to join a LIVE virtual stream of the keynote sessions. The article included several links that I found very useful and wanted to share them with you. This article provides additional information on the updates for Windows 10 through Windows Update. This article provides great tables with the Windows 10 current versions by servicing option servicing option: CB, CBB, LTSB, version: , , OS build number, availability date, and latest revision date and the Windows 10 release history by version OS build number, availability date, servicing option, and corresponding KB Article number and link.
This blog post, written by Michael Niehaus, has links to the above two sites as well as links to the following:. This TechNet article has a great deal of information, explaining the different servicing options in detail. It opens with key terminology to help users distinguish between upgrade and update, and branch and ring.
It provides an overview of all three branches, and a comparison between Current Branch and Current Branch for Business. It provides the break down from what you currently have, what you want to change to, to what you need to do. Hi, my name is Prachi and today I will be talking about a patch installation problem which occurs when multiple patches are installed together.
If you check the update history, you see that it failed to install any update after it tried to install a security update.
The security update, then shows reboot required. This happens because security updates usually require a reboot to commit and will fail any update that is installed after that. Please note that once you encounter a security update, it always does ask for a reboot. In addition to committing the transactions, a reboot is also responsible for committing a task called scavenging.
Please note that scavenging is invoked on system startup when TrustedInstaller starts on boot , system shutdown and idle processing. There is another type of reboot called a non-mandatory reboot which only requires scavenging. You can manually invoke scavenging by stopping and starting the Windows Modules Installer TrustedInstaller service. Please note that scavenging, as the name suggests, removes the unused components and it might help with the problem but only when the reboot required is non-mandatory.
If a third party software is being used for this, the following steps can be added to the schedule:. With Windows Server Technical Preview 5, you can create Nano Server VMs directly in Azure, using the Nano Server image in the Azure Gallery. Download the zip file attached to this blog and unzip its contents to a local folder on your machine. New-AzureRmResourceGroup -Name “MyResourceGroupName” -Location ‘West US’.
New-AzureRmKeyVault -VaultName “MyKeyVaultName” -ResourceGroupName “MyResourceGroupName” -Location ‘West US’ -EnabledForDeployment. Make sure you use the same Resource Group Name in both cmdlets. Select the Azure location that is best for you. psm1 -Verbose. New-NanoServerAzureVM -Location ‘West US’ —VMName “MyVMName” -AdminUsername “MyAdminName” -VaultName “MyKeyVaultName” -ResourceGroupName “MyResourceGroupName” -Verbose. Get-AzureRmPublicIpAddress -ResourceGroupName “MyResourceGroupName”.
Observe the output of this cmdlet and copy the FQDN string, under DnsSettings. It will look something like: “MyVMName. Use it for the secure connection as follows:. Unlike previous Nano Server images in Azure, the optional roles and features are no longer in the image.
NET Framework components correctly validate certificates. An attacker who successfully exploited this vulnerability could inject code into a trusted PowerShell process to bypass the Device Guard Code Integrity policy on the local machine. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. By itself, the CFG bypass vulnerability does not allow arbitrary code execution.
However, an attacker could use the CFG bypass vulnerability in conjunction with another vulnerability, such as a remote code execution vulnerability, to run arbitrary code on a target system.

Well as we all know, what we need in our life at this point are logs, logs, logs, and more logs! But where are the logs for servicing? Although the information is out there, it is surprisingly not so easy to find. If you haven’t already seen this page , you’ll want to head over, check it out, and bookmark it. Tons of great information in here with different levels of content for the beginner to the seasoned IT Pro.
Understanding how servicing works is going to help give you a good foundation on which to troubleshoot these types of failures. There is quite a bit to take in on the aforementioned page, suffice it to say I will provide some cliffs notes here which are not a replacement for reading that content ;. It’s a good idea to read through and understand what each phase is doing, where it takes place, and where the logs for each of these phases are located. Also a key here in finding out what logs were generated and where, is to understand how many reboots have taken place.
Depending on what logs are generated and the content of them , you can deduce which phase the servicing operation failed in. The servicing process reboots once between each phase. This will make more sense later.
Phase 1. DownLevel – This phase is ran in the source OS, this is where all of the install files that are needed are downloaded and prepared for installation. During this phase we mount the SafeOS WIM file AKA the WinPE environment for use after the upcoming READ 1st reboot. After the SafeOS WIM is mounted and updated for use on the system, we dismount it, apply BCD settings making it the default boot entry, suspend Bit Locker, and reboot the machine.
Phase 2. SafeOS – After we come back from the first reboot we are now booting into the SafeOS WIM WinPE that was prepared in phase 1. Once the machine enters WinPE this is where the bulk of the work to service the operating system is done, AKA where the magic happens. There are many, many operations being done in this phase.
Once this phase completes successfully we have applied the new OS, and setup the machine to reboot back into the SafeOS. Phase 3. First Boot – We are now coming back from the second reboot of the servicing process. During the First Boot phase we boot back into SafeOS, new BCD entries are created for the New OS, settings are applied, sysprep is run, and data is migrated. There is quite a bit going on here during this phase as well. Phase 4. Second Boot – During the final phase more settings are applied and more data is migrated, system services are started, and the out of box experience OOBE phase executes.
The culmination of the process is reaching the start screen and eventually the desktop. Phase 5. If you’ve reached this phase, something has gone wrong and your machine is rolled back to the previously existing operating system version.
This implies that somewhere along the line the machine experienced a fatal error and could not continue. Two logs are of immediate interest if you experience a rollback:.
These four main phases are documented on the Windows 10 Troubleshoot-Upgrade-Errors page, and a nice graphic is included at the bottom of the page. For the first three phases you can actually follow along with each item listed in the graphic on the upgrade errors page by looking at the C:Windows. log to see which of the first three phases completed successfully.
The page also gives you an idea of where errors are typically seen and what kinds of things can cause them. Fairly widespread reports of machines taking the upgrade, and eventually rolling back began to trickle in. Results may vary but on average the servicing process can take between hours to complete. The time it takes to complete is dependent on a number of factors, network uplink speed, processor spec, amount of RAM, type of HDD, etc.
In any event, the time that the servicing upgrade took was also compounded by the time the rollback actually took in order to revert the machine to the previous OS. You can get an accurate count of overall servicing time and rollback time by looking at the setupact. log files. In some instances the rollback of machines was still cooking a few hours into the servicing process.
First let me state that there are tons of logs generated during the servicing process; xml, etl, log, evtx, text files, etc. All of them contain information about what happened during the servicing process, some of them are easy to consume and crack open, some of them aren’t as friendly. Review all of the logs, mount the. evtx logs in the event viewer, review the flat text and xml files, and to get into those pesky ETL files you can try converting them to CSV or XML with tracerpt:. exe setup.
etl -of csv -o setup. So we have “all the logs. log and setuperr. log are your friends. They are your go-to. They likely have the information you are looking for or can give you enough information to point you in the right direction or to another log.
After the dust settled we began to look at a sampling of the machines, effectively scraping the C:Windows. Since the following log C:Windows.
log details the first three phases of the servicing process, that’s where we want to start.
