  • Unlink Exploit | heap-exploitation - Dhaval Kapil
    A new fake chunk is created in the 'data' part of chunk1 The fd and bk pointers are adjusted to pass the "corrupted double-linked list" security check The contents of the attacker are overflowed into chunk2's header that sets appropriate prev_size and prev_in_use bit
  • Overview of GLIBC heap exploitation techniques
    When everything is in order, we can trigger the vulnerability by freeing our victim chunk Ultimately, the attacker fully controls the location being written to but not the value itself (the written value will be at the address of the victim chunk)
  • Heap Exploitation: Unsafe unlink Fastbin Corruption – 氷 菓
    To put it simple, the chunk at 0x602000 is available for attacker to manipulate and exist in the freelist of libc at the same time So we can craft the FD pointer of the chunk at 0x602000, and trigger the allocation of pp3 After that we can see a fake chunk (0x602020) is put into fastbin
  • Safe-Linking – Eliminating a 20 year-old malloc() exploit . . .
    In the double-linked list scenario, an attacker that can forge a memory struct, and knows what a valid heap pointer looks like, can successfully forge a valid FD BK pair of pointers that won’t trigger an Arbitrary-Write primitive, but allows a chunk at an attacker-controlled address
  • Heap Exploitation - CTF Handbook - CTF101
    Much like a stack buffer overflow, a heap overflow is a vulnerability where more data than can fit in the allocated buffer is read in This could lead to heap metadata corruption, or corruption of other heap objects, which could in turn provide new attack surface
  • The toddler’s introduction to Heap Exploitation, Unsafe . . .
    As we mentioned in the beginning of the article we fully control the contents of a chunk and due to an overflow bug we can modify the metadata of an adjacent chunk So on our way to successful exploitation we have to pass the unlink check: In order to do the we will do the following: Create a fake chunk inside the controlled chunk
  • Tut09-02: Exploiting Heap Allocators - CS6265: Information . . .
    Now let's take a look at some interesting heap management mechanisms we can abuse to exploit heap The main idea of this technique is to trick free() to unlink the second chunk (p2) from free list so that we can achieve arbitrary write Heap unsafe unlink attack
