I realised while solving the challenges is that sometimes you just want a little bit hint and not a complete walkthrough , So I am listing hints for narnia challenges
These challenges are based on C fundamentals and binary exploitation techniques which usually direct implementation in many cases.
Level0 :
DIY
Narnia1:
Shellcode in environment variable
Narnia2:
Buffer Overflow + Shellcode
Narnia3:
Buffer Overflow , symlinks
Narnia4:
No hints for this
Narnia5:
https://www.owasp.org/index.php/Format_string_attack
http://forum.ouah.org/FormatString.PDF
Narnia6:
Function Pointer can be overwritten
https://www.exploit-db.com/docs/28553.pdf
Narnia7:
Format String Vulnerability
ltrace
Narnia8:
If you want more detailed explanation or have any doubts or are stuck somewhere , welcome to comment below.

this is great! This is all I want, a small hint, in particular, i found ltrace hint for level 7 is super useful for me, because i cannot figure way out to see which parameter should I refer too, thanks.
