lab6B appears unsolvable #7

Closed ykram closed 9 years ago

ykram commented 9 years ago

It appears the source to lab6B was possibly modified before release as it requires editing before compilation. Furthermore, lab6B appears to have an issue that may make it unsolvable, specifically when attempting RCE / leakage.

@ykram - This seems to be the case, others ran in to it as well. In the meantime if you'd like, you can find the original binary without the issue here (http://shellspace.net/files/lab6B). Make sure you run it on the VM.

lab6B has been tweaked accordingly. This level was very touchy, and something changed that shouldn't have during code refactoring before it was released.

The VM image will probably be updated soon too as we have had 2-3 minor bugfixes across the wargame now.

Confirmed it's working as intended. Thank you for providing an updated binary.
