Who is Vulnerable?
Vulnerability Description Microsoft Office is a popular productivity application suite released by Microsoft Corporation. It includes a word processor, a spreadsheet application, a presentation editor, and a number of other applications and components. There exists a vulnerability in Microsoft Office products. The flaw is due to improper handling of Microsoft Office files containing malformed records. An attacker can exploit this vulnerability by enticing an unsuspecting user to open a malicious Office document. This flaw may allow the attacker to execute arbitrary code in the context of the currently logged-in user.
