<div dir="ltr">Hello,<div><br></div><div>The deadline of Homework1&2 was postponed until 4th December 2013, but this date was not updated on courses site (<a href="http://curs.cs.pub.ro">curs.cs.pub.ro</a>). It will be updated or it remains the same?</div>
<div><br></div><div><br></div><div>Refering to Homework 1, lvl07 I have been trying to solve it for several days, but in vain. I tried to do a shellcode which print the content of stack but it does not work given SIGVFAULT. I mention that the shellcode is 64 bit one and it correctly works when it is assembled and linked with as and ld and I run it on given machine directly from elf. Additionally, I made another shellcode that print hello world, but when it passed to stdin of the lvl7 the same problem appears. I notice that all registers were zero, so what method should us approach?</div>
<div><br></div><div>I can remark from the previous attempts that I might use a wrong method. I can't advance to next level, because I can hardly to find the solution for this one. </div><div><br></div><div>Could you offer me and my colleagues some advice that will give us some new directions of research for this tasks? Some links or some example.</div>
<div><br></div><div>Thank you in advance!</div><div><br></div><div>Cosmin</div></div>
