Who is Vulnerable?
Vulnerability Description	Microsoft Office Access, previously known as Microsoft Access, is a relational database management system from Microsoft which combines the relational Microsoft Jet Database Engine with a graphical user interface and software development tools. There exists a buffer overflow vulnerability in Microsoft Jet Engine. The flaw is due to boundary errors when processing MDB database files. A remote attacker can exploit this vulnerability by enticing the target user to open a crafted MDB file. Successful exploitation may lead to arbitrary code execution in the security context of the logged in user. In case of an attack where code injection and execution is successful, the behavior of the target is entirely dependent on the intended function of the injected code. The code in such a case would execute within the security context of the current user. In case of an attack where code injection is not successful, the affected Microsoft Access application will terminate abnormally.
