Some users has reported that they are prompted that the system detected an overrun of a stack-based buffer for odd reasons. In this post, you will fully learn about this issue and get several possible solutions provided by MiniTool Software.

About Stack-based Buffer Overrun Error

Stack-based buffer overrun (or stack-based buffer overflow) is a kind of bug indicating that a program writes more data to a buffer located on the stack than that is actually allocated for the buffer. It is a general programming malfunction.

This issue might happen to your driver and lead to the driver overran stack buffer blue screen of death error. But more commonly, it’s related to your applications, and once it comes up, the adjacent data on the stack might be corrupted and the program is likely to crash or operate improperly.

The stack-based buffer error has been reported by plenty of users on the forum, and a case is displayed here:

Basically, I keep getting an error and the error is this – “The system detected an overrun of a stack-based buffer in this application. This overrun could potentially allow a malicious user to gain control of this application. (c0000409)” I have a build that can run AAA games ultra, so it’s not my hardware. I’m running it off my SSD; all drivers are updated; Windows 10 64-bit is fully updated; I’ve uninstalled the game multiple times and let the cache re-download. Does anyone have any advice that could possibly give me?    — from

stack-based buffer overrun detected

According to the reports from the users who are experiencing the issue, the overrun of a stack-based buffer error message mainly appears in following 2 situations:

  • After opening computer in Safe Mode due to the Windows running into certain problems, such as explorer.exe keeps opening.
  • When trying to install the Twitch or Discord desktop applications.

you might have tried various solutions but in vain. To get rid of this issue, I collect some possible methods and put them altogether in this post. Hopefully, they could be helpful for you.

Note: If this error prevents you from accessing the apps or settings normally, you might need to boot your computer into Safe Mode and then try the following solutions. What’s more, as this issue might lead to data loss, you’d better recover the lost data before you take action to fix it.

Fix 1: Scan Your Computer for Virus or Malware

As the error message suggests, the specific program might be running with special privileges, and give the control to a malicious user, and thus be affected by certain malicious code or program. So, it’s necessary to scan your computer for any potential virus or malware.

It’s recommended to perform the Windows Defender Offline scan and here’s how to do it:

Step 1: Right-click the Start button and choose Settings from the menu.

Step 2: Navigate to Update & Security > Windows Security.

Step 3: Click Virus & threat protection in Protection areas section of the right pane.

Step 4: When you get the Windows Defender Security Center window, click Run a new advanced scan.

Step 5: Then, choose Windows Defender Offline scan and click Scan now button.

perform Windows Defender Offline scan

This kind of scan will help you remove malicious software that is difficult to remove, and it requires a restart to complete the process. It takes about 15 minutes and you should wait patiently until the scanning is finished.

Fix 2: Run SFC And DISM Command

In addition, the corrupted system files or Windows image files could also lead to buffer overrun detected on your computer. To fix stack-based buffer overrun issue in this case, you can try using System File Checker (SFC) and Deployment Image Servicing and Management (DISM) utilities.

Note: As running DISM requires the internet connection, you should start computer in the Safe Mode with Networking if you cannot boot it normally.

Step 1: Press Windows + R to invoke Run dialog.

Step 2: Input cmd and press Ctrl + Shift + Enter to open Command Prompt as administrator.

Step 3: Type the command sfc /scannow and press Enter to start scanning the system files. Once any corrupted files are found, this tool will replace them with the cached copies and the scanning process will take some time. If this resolves the issue successfully, it’s fine. Otherwise, you need to continue with the next step.

run SFC scan

Step 4: Input the following command lines and press Enter after each to execute them:

  • DISM /online /Cleanup-Image / ScanHealth
  • DISM /Online /Cleanup-Image /RestoreHealth

After the operation is completed successfully, exit the window and restart your computer. Then, check if the stack-based buffer overrun issue has been resolved. Besides, you can run the SFC scan again as your needs.

Fix 3: Clean Boot the Computer

It’s possible that the system might detect an overrun of a stack-based buffer if a certain third-party application which starts with the system gets corrupted or runs into problems. In this case, you can clean boot your computer to prevent all the third-party programs or services from starting with the system. To do that, just follow the instructions below:

Step 1: Press Windows + S, input msconfig and click System Configuration from the search results to open it.

Step 2: Go to Services tab, check Hide all Microsoft services and click Disable all button to stop all the third-party services.

disable third-party services

Step 3: Switch to Startup tab and click Open Task Manager.

Step 4: Then, select a program and click Disable. Repeat the operation to other programs in the list to prevent these third-party apps from starting with the system and confirm changes.

Step 5: When you back to the System Configuration window, click Apply and OK to save the changes.

After that, restart your computer to take effect the changes and the issue should have been resolved. By the way, you can re-enable these programs one by one to find out the problematic one and then keep it disabled or remove it.

Fix 4: Perform System Restore (If Available)

If you have enabled System Protection feature to protect your computer and created a restore point at least before the stack-based buffer overrun issue occurs, perhaps you can try reverting your computer to a previous restore point to fix the problem.

Note: If you are unable to get into the Safe Mode, you can choose System Restore module directly in the Advanced Options page before going to Startup Settings.

Step 1: Type restore in the Search box and choose Create a restore point from the results.

Step 2: The System Properties windows will appear and you need to click System Restore button under System Protection tab.

click System Restore

Step 3: Skip the welcome page. Choose the latest restore point and click Next button.

Tip: To make sure the programs to be uninstalled or changed during the process, just click Scan for affected programs.

choose a restore point

Step 4: You will be required to confirm the restore point in the next page. Make sure all the tasks are saved and then click Finish button to execute this operation which needs to restart your computer to apply changes.

After that, the issue should be removed hopefully.

Fix 5: Try Startup Repair

As mentioned before, if buffer overrun is detected by your system, it is possible that your computer gets frozen or cannot boot. If the above methods cannot fix the issue for you, it’s high time to try the Startup Repair.

To do that, you don’t have to start into the Safe Mode and here are 2 common options for you – perform the operation in Advanced Startup Settings or using Bootable Media. Let’s see them one by one.

Option 1: Perform Startup Repair in Advanced Startup Settings

Step 1: Forcefully shut down your computer for 3 times to enter Windows recovery environment and then click See advanced repair options.

Step 2: Go to Troubleshoot > Advanced options and choose Startup Repair.

Option 2: Perform Startup Repair Using Windows Installation Media

If you cannot access the recovery environment using the common way, you can choose to employ an installation media, such as USB bootable media.

Step 1: Burn a USB installation media using Windows 10 Media Creation Tool in a normal computer.

Step 2: Connect the bootable USB drive to the problematic device and boot from it by changing the BIOS settings.

Step 3: When you get the Windows Setup window, enter your language and other preferences and click Next button.

Step 4: Click Repair your computer to enter the recovery environment and launch Startup Repair by referring to the steps in the above content.

Fix 6: Back up Data and Reinstall Your Windows

If none of the above methods help to get rid of stack-based buffer overrun error message, you might need to reinstall Windows to make your device work normally again.

This is a last resort, as reinstalling Windows will result in data loss on the system disk. So, you have to backup or transfer the needed files in advance. If there are a large number of files you want to backup, the easiest way should be back up the entire disk. To achieve that, you can use MiniTool Partition Wizard utility.

Step 1: Register to MiniTool Partition Wizard Pro Ultimate edition with a purchased license key.

Note: If you cannot access the desktop normally, you need to create a bootable media in another normal computer. Then, boot your computer from the media and enter MiniTool recovery environment to execute the following operation.

Step 2: In the main interface, select the system disk and click Copy Disk from the left pane.

Step 3: Select the target disk to hold the backup and click Next.

Warning: All the data on the target disk will be destroyed, so make sure there’s not important data.

Step 4: Choose the Copy Options (the default setting is fine), confirm the size and location of partitions on the new disk and click Next.

Step 5: Read the information about how to boot from the destination disk and click Finish. After back to the main interface, click Apply to execute the pending operation.

Thanks to MiniTool Partition Wizard, I have backed up all the data on the drive quickly.Click to tweet

Now that you have backed up the system disk, you can reinstall Windows without any worries.

To do that, you can continue using the Windows installation media you create in previous mentioned method. After entering the Setup windows, please click Install now instead of Repair your computer, and then follow the given instructions to complete the installation.

“The system detected an overrun of a stack-based buffer in this application” is really an annoying problem for me. Luckily, I have fixed it by myself with one of the methods provided in this post.Click to tweet
