CVE-2017-0261 is a use-after-free vulnerability in Encapsulated PostScript (EPS) processing in Microsoft Office 2010 SP2, Office 2013 SP1, and Office 2016. Crafted embedded EPS content combines PostScript save/restore behavior with the forall operator to create a use-after-free condition and obtain a memory read/write primitive. Exploitation constructs a ROP chain and a forged file object, then redirects execution through the closefile operator to execute shellcode. Malicious Office documents exploited this vulnerability in targeted attacks involving Turla and an unidentified financially motivated actor.

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.
