CVE-2017-0261 is a remote code execution vulnerability in Microsoft Office 2010 SP2, Office 2013 SP1, and Office 2016 involving the handling of embedded Encapsulated PostScript content. The flaw is a use-after-free condition in EPS processing associated with the PostScript restore operand. Exploitation abuses PostScript save/restore behavior together with forall to free an object and subsequently reuse it, creating a controllable read/write primitive. Observed exploit chains used this primitive to construct a ROP chain, forge a file object, and pivot execution through a PostScript file-handling operation to run attacker-controlled shellcode during document rendering. The vulnerable EPS content is processed through the Office EPS rendering path, enabling code execution when a malicious Office document is opened or otherwise rendered.

This repository contains a proof-of-concept exploit for CVE-2017-0261, a vulnerability in Microsoft Office's handling of Encapsulated PostScript (EPS) files. The main payload is 'done/poc.eps', a large EPS file containing complex PostScript code and embedded shellcode designed to trigger arbitrary code execution when processed by a vulnerable application. The Makefile in 'LoadEps/' appears to be for building a related loader or analysis tool, but the main exploit is the crafted EPS file. The README provides a brief description and context for the exploit. There are no network endpoints or external IPs/domains; the attack vector is via a malicious file. The exploit is a POC and does not appear to be weaponized or part of a larger framework.
