Xpdf Docker Images

This repository contains docker images for Xpdf version 4.04, which is vulnerable to CVE-2022-30524.

Building the Images 📦

This repository contains the image in 3 flavours:

• bullseye/gcc: Debian "bullseye", built with gcc
• bullseye/afl: Debian "bullseye", built with afl-clang-fast++ (debug profile)
• focal/afl: Ubuntu 20.04 LTS (Focal Fossa), built with afl-clang-fast++ (debug profile)

Flavours that are just aliases to other flavours:

• bullseye → bullseye/gcc

Their Dockerfile are present in their respective directories in dockerfiles/ directory.

The repository is packaged with a Makefile for easier building of the images. To build any image, run the following command:

make '<flavor-name>'

# Eg. if building the focal/afl profile
make focal/afl

# If you want to build all the images
make

This will generate a Docker image interiit/xpdf:4.04-<flavor>. Running just make builds all the images.

Checking Integrity 🔍

The repository contains the vulnerable version of Xpdf, as well as a few sample PDF files. The pdftotext binary should work on pdfs/dummy.pdf, but should abruptly give segmentation fault on pdfs/poc1.

To make sure that the files are not corrupted/altered, run make check. If the command errors, it might mean that the files may be corrupted.
