+/**
+ * Author : 0xd3xt3r
+ * 
+ * Double free vulneribity in on tcache bins is mitigated in 2.27 and later
+ * can be seen in commit bcdaad21d4635931d1bd3b54a7894276925d081d
+ * This has fixed the attack which gives arbitrary write vulneribity in glibc
+ * double free. This attack will demonstrate how we can bypass this mitigation
+ * and get an arbitrary write with the new mitigation applied.
+ * 
+ * This Attack works as follows:
+ * 
+ * 1. Free an allocated chunk
+ * 2. Change the size of the chunk and either by realloc or overflow from the
+ *    previous chunk
+ * 3. Free the same chunk again, now you have same chunk in two tcache bins.
+ * 4. Request the chunk from either of the bins
+ * 5. Now write the fake chunk address in the first 4/8 bytes of the newly
+ *    requested chunk. This will poison the tcache list having this chunk.
+ * 6. Subsequent request to the tcache list containing the poisoned chunk
+ *    will return our target memory area.
