+<h2>3.03</h2>
+<p>
+  3.03 has a couple of additional tricks going on. There are no jump targets which lie within our controlled range from any buffer overflows, however the jump target 0x15ea540 is very close to the beginning of our IFO file contents (0x15ea620).
+</p>
+
+<p>
+  The memory between the jump target and the start of the IFO (0x15ea540 - 0x15ea620) is all zeroes, so that's just a NOP-sled. Then the IFO header "DVDVIDEO-VMG" turns out to decode to a conditional relative branch which not only happens to be taken, but also jumps to fully controlled contents later in the IFO:
