Overview

Fuzzing PDFs like its 1990s

This is the fuzzer I made to fuzz Preview on macOS and iOS like 8years back when I just started fuzzing things.

Some disclosed vulnerabilities:

  • CVE-2015-3723
  • CVE-2016-1737
  • CVE-2016-1740
  • CVE-2017-7031

Info

The basic idea of this fuzzer was to mutate the streams of the pdf files without screwing the PDF Structure as a whole. I collected some hundreds of PDFs and converted the PDFs to Python script using Didier Stevens's pdf-parser -g flag. The fuzzer uses cPDF that I modified to mutate the stream using Charlie's 10liner, every time I try to generate a PDF file.

This made it really easy to mutate the stream and create the PDF file from the fuzzing server.

I used Charlie's 10liner for mutations:

fuzzFactor = 30
def bitman_(buf):
    buf = bytearray(buf.encode())
    try:
        numwrites = random.randrange(math.ceil((float(len(buf))/fuzzFactor))) + 1
    except:
        numwrites=10

    for j in range(numwrites):
        rbyte = random.randrange(256)
        rn = random.randrange(len(buf))
        buf[rn] = rbyte
    return str(buf)

Usage

Meh! it's a python script, use it as you wish!
