Jump-Oriented Programming: Harder than ROP because the registers need to be prepared individually? + Turing complete, but large overhead/slow?

Full title: Jump-Oriented Programming: Is it harder than traditional return-oriented programming because you need to manually prepare all the addresses and registers or is there a different reason?
And does that mean that a large percentag… Continue reading Jump-Oriented Programming: Harder than ROP because the registers need to be prepared individually? + Turing complete, but large overhead/slow?

When gets reads a string, it does not read \x00, which is the NULL character. So how to separate two different addresses to complete ROP?

First I used ROPgadget to find two assembly instructions:

They are at 0x401270 and 0x40133b.
Then I tried to put them at the top of the stack, but because the gets instruction does not read the \x00 character… Continue reading When gets reads a string, it does not read \x00, which is the NULL character. So how to separate two different addresses to complete ROP?
