Vulnerability Details
The vulnerability is caused when Microsoft Groove 2007 incorrectly restricts the path used for loading external libraries. An attacker could convince a user to open a legitimate Groove-related file (such as a .vcg or .gta file) that is located in the same network directory as a specially crafted dynamic link library (DLL) file. Then, while opening the legitimate file, Microsoft Groove 2007 could attempt to load the DLL file and execute any code it contained. Successful exploitation of this vulnerability could allow the attacker to take complete control of an affected system.

Protection Overview
This protection will detect and block the transferring of suspicious DLL files over CIFS and Webdav.
