[gr00vy <groovy2600 () yahoo com ar>]

Hi all.

Im having some problems to exploit a buffer overflow in Polymorph v0.4.0
I cant spawn a shell. I dont know why. I hope someone can helpme.

I have attached my exploit based on the paper of Core Security,
"Vulnerabilities in your code - Advanced Buffer Overflows"

Best regards
