 Application:   IPD up to 1.4 (http://www.pedestalsoftware.com/)

Overview:
- ---------

The IPD (Integrity protection driver) is an Open Source device driver
designed to prohibit the installation of new services and drivers and
to protect existing driver from tampering. It installs on Windows NT 
and Windows 2000 computers. 

In its security approach IPD hooks some kernel mode funtions and filters
them allowing or not their original purposes based on IPD's security 
policy.

IPD suffers from an unvalidated pointer referencing in some of this kernel
hooks. 


Technical description:
- ----------------------

The IPD (Integrity protection driver) is an Open Source device driver
designed to prohibit the installation of new services and drivers and
to protect existing driver from tampering. It installs on Windows NT 
and Windows 2000 computers. 

IPD is available for download at:

         http://www.pedestalsoftware.com/download/ipd.zip

In its security approach IPD hooks some kernel mode funtions and filters
them allowing or not their original purposes based on IPD's securit 
policy.

IPD suffers from some unvalidated pointer referencing in some of this kernel
hooks. In example IPD hooks ZwOpenSection declared as follows:

        NTSTATUS ZwOpenSection(HANDLE Handle, DWORD mask, DWORD oa);

The problem exists because IPD does not properly check wether "oa" pointer
is valid or not. Any local and unauthorized user can crash the system with
some simple coding skills.

Sample exploitation cand be found:

Recommendations:
- ----------------
Since the vendor has discontinued the development and support of IPD,
NGSEC recomends to uninstall IPD or perform a deep source security audit
before re-enabling it.
