Matthew Murphy has reported a security issue in Windows, which potentially can be exploited by malicious, local users to gain knowledge of sensitive information.
The problem is caused due to an error in the NTFS file system when handling file handles that are not properly closed before the system is shutdown (e.g. during power/hardware failures, kernel blue screens, or shutdowns initiated with the Win32 API "InitiateSystemShutdown()", or due to a service that is prematurely terminated during system shutdown).
This can cause the file system to incorrectly assign disk blocks to files before they have been initialised, thereby potentially disclosing sensitive information, if a malicious, local user is able to read one of these files.
Solution: Grant only trusted users access to vulnerable systems.
