Loading vulnerability…
A stack-based buffer overflow exists in CoolPDF Reader 3.0.2.256. The vulnerability is triggered when the application processes a PDF document containing a specially crafted stream, leading to a buffer overflow in the PDF reader component. This allows an attacker to overwrite stack memory, potentially redirecting execution flow.

This repository contains a single Metasploit module (coolpdf_image_stream_bof.rb) that exploits a stack buffer overflow vulnerability (CVE-2012-4914) in Cool PDF Reader versions prior to 3.0.2.256. The exploit works by generating a malicious PDF file (default name: msf.pdf) containing a specially crafted JPEG image stream. When a user opens this PDF in a vulnerable version of Cool PDF Reader on Windows XP SP3 or Windows 7 SP1, the buffer overflow is triggered, allowing execution of arbitrary code embedded as a Metasploit payload (up to 2000 bytes). The module leverages Metasploit's PDF and fileformat mixins and is fully integrated into the Metasploit framework, allowing for customizable payloads. The attack vector is local, requiring user interaction to open the malicious file. The repository is operational and suitable for demonstrating code execution via a crafted document.
