Title: Stack Overflow in XPDF (AddressSanitizer: stack-overflow on address 0x7fffff7feef8)

Description:
A stack overflow vulnerability was discovered in XPDF (version 3.02 or 3.04) when processing a crafted PDF file. This issue occurs due to a missing or invalid CharProcs dictionary in a Type 3 font, which leads to an infinite loop and ultimately a stack overflow. The issue was detected using AddressSanitizer (ASan).

Steps to Reproduce:

  1. Compile XPDF with AddressSanitizer enabled.
  2. Execute the following command on a crafted PDF file: 
    ./pdftops ./poc /dev/null

Crash:

➜  xpdf ./pdftops ./crashes/id:000011* /dev/null
