[Pwnable] Heap of Secrets

#1

Time to step up the game. Keep in mind there is more than one way to solve it. Good luck.


Rules

  • Feel free to pwn the binary on Ubuntu 16.04 or 17.04. Extra credits if you pwn it on 17.04.

  • Don’t ask me for hints. Hints will only be given 1 month after the challenge’s release as long as there are still 0 solves and demand for a hint.

  • Don't post your exploit below (with or without the spoiler tags)! This will not help those who still struggle. If you do pwn the binary, make sure to pm me your exploit with an explanation, and once I evaluate it, I’ll post in the comment section that you successfully pwned it providing your alias.

Hmmmm, seems like you haven’t even solved it yourself yet. =p


#3

I don’t get it. Why would I create and post a pwnable if I haven’t made sure it’s solvable? :stuck_out_tongue:


#4

If i’m not mistaken, I believe @0x00pf did that at one point in the past 2 yrs.


#5

I can pm you my PoC if you’re in such doubt.


(pico) #6

I think I have done that a couple of times… You may be referring to this one:


#7

Yup, that’s the one.


#8

There will be a time when I finally pick up heap shenanigans and I will do all those challenges @_py!
Promised :smiley:
