Help with setuid

Hi,

I think I did the buffer overflow correctly and I am already getting the shell. However, I am getting a shell of my own user and without permission to read solution.txt. What am I doing wrong?

Thank in advance.

What you are doing wrong is not knowing something about how (ba)sh handles its invocation. Perhaps try the manual. Smile

There are several ways around this, with and without knowing.
