Shellcode it is not closed properly in certain conditions #81

Closed jarilaos closed 3 years ago

jarilaos commented 3 years ago

If the format used is c or ruby the shellcode it is not closed properly when the last string is longer than 14 bytes.

If the length of the last string is 15 bytes the shellcode ends as follows: "\xc3\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00;

If the length of the last string is 16 bytes the shellcode ends in a new line as follows: ";

Something similar happens with py_template.

It causes that it is not possible to compile.
