Electrical leak pointer for sieyuan

2020-7-17When a class includes a pointer it is the pointer that is a member of foo, the thing the pointer points to is not (excepting pathological cases) a part of foo even if you new it in foo::c'tor and delete it in foo::d'tor (in which case foo is responsible for it and notionally owns it). – dmckee --- ex-moderator kitten Apr 23 '13 at 1:18

  • exploit - How leaking pointers to bypass DEP/ASLR

    2021-2-5The only way to reliably bypass DEP and ASLR is through an pointer leak. This is a situation where a value on the stack, at a reliable location, might be used to locate a usable function pointer or ROP gadget. Once this is done, it is sometimes possible to create a payload that reliably bypasses both protection mechanisms.

    This generally would make sense: unless the pointer is the null pointer, it must be storing the address of another node, so we should delete that node. However, C++ has a very nice feature: You can always call delete on the null pointer, and nothing will happen. Thus, the above code can be written without the check:
