Windows Bug: Web pages can crash your computer


Web sites can crash computers with Windows Vista, 7 and 8. Guilt is a bug discovered by a Russian security company. Windows locks access to certain system resources, such as the master file table. If a website tries to access it, there may be problems.

Windows systems with Vista, 7 or 8 can crash when calling specific websites. The Russian security company Aladdin RD found this out and published details on an IT blog. Therefore, Web pages could access the main files of the Windows system drive. This is usually the so-called master file table (MFT) of the NTFS file system. However, the associated driver does not allow such accesses, resulting in blockage and subsequent freezing of the computer.

Corresponding web pages use an error that can change the path to an image and contain the string “$ MFT”. However, this sequence does not describe a directory, but the file of the drive that contains the location of all the data on the hard disk. Access to this file is not intended, Windows usually hides it.

Proper protection against the use of the bug can already be the choice of the right browser. As Ars Technica reports, crashing can not be done with any browser because modern programs block access to system resources. However, Internet Explorer does not belong to it.

According to the report ( machine translation ) on the mentioned IT blog, Microsoft is aware of the problem. However, there is no information about scheduled troubleshooting or updates for the next patch day. This is always planned for every second Tuesday of a month. At the moment, this means June 13th. Until then, it is still over two weeks. Anyone who does not work with Internet Explorer or operating systems before Windows 10, should be on the safe side, according to current knowledge.
