CVE-2005-2145

Description:
Tri Huynh has discovered two vulnerabilities in Prevx Pro 2005, which can be exploit to bypass security features provided by the product.
1) Incorrect handling of memory mapped files allows protected files that are mapped into memory using "MapViewOfFile()" to be written. This can be exploited to bypass the product's file protection security feature.
2) The driver does not validate the sender of received device I/O control codes. This allows a user-space program to bypass the product's security features by sending specific I/O control codes to the driver.
The vulnerabilities have been confirmed in version 1.0. Other versions may also be affected.
Solution:
Do not run untrusted programs.
The vendor recommends replacing the vulnerable product with the Prevx1 product.
