The vulnerability is due to the application loading a malicious copy of a specific, nondefined DLL file instead of the DLL file it was expecting. An attacker could exploit this vulnerability by placing an affected DLL within the search path of the host system. An exploit could allow the attacker to load a malicious DLL file into the system, thus partially compromising confidentiality, integrity, and availability on the device.
