Microsoft Office Malformed EPS File Remote Code Execution
CVE-2015-2545 is a remote code execution vulnerability in Microsoft Office’s handling of Encapsulated PostScript (EPS) 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 Office 2013 RT SP1. An attacker can embed a specially crafted EPS image in an Office document, including DOC/DOCX or Web Archive/MHTML-based delivery formats, and trigger arbitrary code execution when the document is opened and the malformed EPS is processed. The vulnerability was patched by Microsoft in MS15-099 on 2015-09-08. The content also notes widespread in-the-wild exploitation by multiple threat actors and exploit builders, including use in targeted spearphishing campaigns and exploit-document kits.
