Secunia

A vulnerability has been identified in Microsoft Windows NT which possibly could allow malicious users to cause certain applications to fail.

The problem is that the file management function may free memory that it doesn't own if it receives a malicious request. This does not affect the operating system but only the application which called the file management function.

Microsoft did not provide any example of an application or configuration which is vulnerable to this issue, but stated that this possibly could affect Internet Information Server 4.0 in a non-default configuration.
