How to Solve a Buffer Overrun Detected Problem

How to Solve a Buffer Overrun Detected Problem

Buffer overrun detected problems may occur when unsafe data is permitted by software that is coded in C or C++. This problem can happen in all operating systems, but it is particularly common on Windows-based operating systems. The unsafe data that is introduced externally can exploit vulnerabilities in software or cause program crashes. This can permit malicious software to enter and harm your computer.

Buffer overrun detected error messages should be corrected as soon as possible to ensure that greater security issues do not arise. Follow the instructions below to solve the buffer overrun detected problem.

Instructions to Solve Buffer Overrun Detected Problem

There are a few steps to follow in order to fix the buffer overrun detected problem. The skill level of this solution is considered moderate, and it should be able to be performed by most users. These steps can only be performed on Windows Vista, Windows 7, or Windows XP.

Follow these steps to fix the buffer overrun detected problem:

   1. First you need to download the latest security patches, service patches, and hotfixes for your version of Windows. You can do this through the Windows Update service. There are a couple steps to follow to download these patches.

a. If you have Windows XP, then click on Start, All Programs, Accessories, then Windows Update. If you have Windows Vista or Windows 7, click on Start then Windows Update.

b. Select all of the important/critical downloads. Wait for Windows to download and install these updates. You may be prompted to restart your computer several times, depending on how many updates are available.

   2. If it is available, download and install a newer version of the non-Microsoft software. You can do this by accessing the integrated Check for Updates feature, or by visiting the software vendor’s website and installing the latest version.
   3. If your firewall is not currently enabled, then install or turn on your firewall. You can switch on the Windows Firewall by following these steps:

a. Click on Start and then Control Panel.

b. Click on Classic View in the left column if applicable. Double-click on Windows Firewall.

c. If you use Windows Vista or Windows 7, then click Turn Windows Firewall On or Off in the left column. Then select On or Turn on Windows Firewall then OK. If you use Windows XP, then in the General tab click On.

After your firewall is enabled, it should block the ports that the potential buffer overrun exploiters will request when they transmit malicious data.

How to Solve Buffer Overrun Detected Problem: Microsoft Visual C++ Runtime Library

CyberLink Media Service, or Clmlsvc.exe, scans system files for new media files. If Clmlsvc.exe comes across a path that is more that 255 characters long, then it overflows the buffer. When this happens, you will see the following message on a computer that runs Windows Vista:

“Microsoft Visual C++ Runtime Library
Buffer Overrun detected!
Program: <program path>\CLML\CLMLSvc.exe

A buffer overrun had been detected which has corrupted the program’s Internal state. The program cannot safely continue execution and must now be terminated.”

This issue can occur when you install an application or install a Windows Vista service pack. It can also happen when you install a software update using Windows Update or Microsoft Update. The error could also occur when you upgrade your computer to Windows 7 from Windows Vista.

If you are performing one of the actions listed above, then the error message can be safely ignored. For example, if the error message comes up during the installation of Windows Vista Service Pack 2 (SP2), then you can click on OK to close the error message box. The installation of Windows Vista SP2 will continue and SP2 will be installed correctly.
