Microsoft Windows fails to properly create entries in the Local Descriptor Table (LDT)

Vulnerability Note VU#122076

Original Release Date: 2004-04-14 | Last Revised: 2004-04-14


Microsoft Windows NT4.0 and Windows 2000 contain a vulnerability that could permit a local user to gain elevated privileges on the system.


Microsoft Windows NT4.0 and Windows 2000 provide an API to the kernel to create Local Descriptor Tables (LDT) for applications. A failure to filter content in the programming interface could permit an attacker to access and modify protected memory space. This could result in the attacker gaining elevated privileges. The vulnerable function in the API is NtSetLdtEntries. For more details, please see Microsoft Security Bulletin MS04-011 and eEye Digital Security Advisory [AD20040413D].


A local user may be able to gain elevated privileges on the system.
