Vulnerability Details The vulnerability is due to an error in the way Microsoft VBA restricts the path used for loading external libraries. A remote attacker could exploit this issue by enticing a user to open a legitimate Microsoft Office-related file (such as a .docx file) that is located in the same network directory as a specially crafted dynamic link library (DLL) file. Successful exploitation will allow an attacker to execute arbitrary code on an affected system, in the security context of the logged on user. |
