Who is Vulnerable?
Vulnerability Description	EPS is a standard file format for importing and exporting PostScript files. It is usually a single page PostScript program that describes an illustration or an entire page. An EPS file can contain any combination of text, graphics and images. A remote code execution vulnerability was reported in the way Microsoft Office handles malformed graphics image files. The vulnerability is due to a memory corruption error when a malformed EPS image file is opened by any of the affected Microsoft Office applications. A remote attacker could trigger this flaw by convincing a victim to open a specially crafted EPS image file. Successful exploitation of this issue may allow the attacker to take complete control of the affected system. There are cases in which certain traffic, although not intended for malicious use, is very unsafe, since it may transfer shellcode which is undetectable by IPS.
