Microsoft Office Malformed EPS File Vulnerability
CVE-2015-2545 is a remote code execution vulnerability in Microsoft Office’s handling of Encapsulated PostScript (EPS) image content, specifically described in the provided content as an EPS parsing flaw in the EPSIMP32.FLT module. Affected products include Microsoft Office 2007 SP3, 2010 SP2, 2013 SP1, and 2013 RT SP1. The vulnerability is triggered when Office processes a specially crafted EPS image embedded in a document, including DOC/DOCX and Web Archive/MHTML-based delivery formats observed in the wild. The supplied reporting states that exploitation used malformed PostScript/EPS content and was widely weaponized in targeted spear-phishing campaigns. Successful exploitation results in arbitrary code execution in the context of the user opening the malicious Office document.
