Who is Vulnerable?
Vulnerability Description	A remote code execution vulnerability exists in the way that certain products handle the loading of DLL files. Certain applications improperly restrict the path used for loading external libraries. A remote attacker could exploit this vulnerability by manipulating a user to open a legitimate file that is located in the same network directory as a specially crafted DLL file. Upon opening the legitimate file, the application may attempt to load the malicious DLL and execute any code it contains. Successful exploitation of this vulnerability will allow an attacker to take complete control of an affected system.
