Custom malloc()/free() implementation
This library contains a custom malloc() and free() implementation. In 3.35 void *malloc(int size, char flags, int align) is located at offset 0x57b8 and void free(void *ptr) at 0x5a40. Another way to find them is search for immediate value 0x4D61416B, one will be in a data segment and referenced by malloc, another is an immediate value used from free.
Here's an illustration of how allocated/free chunks work:
The primary problem with exploiting heap overflows are the red "heap cookies": BuSy, MaAk, FrEe. When a chunk is allocated and the freelist is iterated it checks for the presence of "FrEe" on every iterated chunk. When a chunk is freed, it checks for "BuSy" and "MaAk". If cookies don't match, the code does an *(int*)0 = 0 which crashes the system.
Note that "MaAk" is appended right after the user provided "size" bytes, so it might not be aligned.
