Vulnerability explanation There is a 4bytes value in the undocumented rcsL chunk in our sample director movie and it may be possible to find similar rcsL chunks in other director samples.

The 4bytes so called value can be manipulated to reach the vulnerable part of function Here is the function:. By manipulating the argument in rcsL chunk we reach to an indirect call that is based on our arguments:.

EAX register is set with second argument that we have control on it and ESI is first argument of the function and is a pointer to a dynamic allocated structure in heap.

Exploitation: For exploitation purpose because we don't have a fixed address in our call we cannot control the execution flow to an exact value but we can jump to a specific range because we have control on first bytes of the pointer of indirect call. An important hint here is that because we call the indirect pointer the EIP is set to nops itself. In our test sample we used 0a0a0a0a as both base range of heap spray and nopslides because 0a0a opcode is an OR instruction on some unimportant registers.
