All of this can be done in .c or .cpp. Part 1: Write a memory dump: void dumper( unsigned char *x, int n ) Which prints out memory like this, in hexadecimal. Address +x00 +x04 +x08 +x0c 7fffb80aaab0 00000000 00000000 004003e3 01234567 7fffb80aaac0 b80aabf8 00007fff b80aaabc 00007fff 7fffb80aaad0 3a40fb88 00000030 b80aaabc 00007fff 7fffb80aaae0 b80aab00 00007fff 00400537 00000000 7fffb80aaaf0 b80aaafc 00007fff 00000000 01234567 7fffb80aab00 00000000 00000000 3a41ecdd 00000030 7fffb80aab10 00000000 00000000 b80aabe8 00007fff 7fffb80aab20 00000000 00000001 00400514 00000000 x is a pointer to somewhere in the stack (the address of any automatic variable), n is the number of 16 byte addresses to print. x could point to anywhere. Whatever x is, please round it down to a multiple of 16 so that every starting address ends in 0. The column header is not required. The first column is the memory address of the first four byte dump. The next four columns are the data at the addresses +0, +4, +8 and +12. In the printout, remember to reverse the order of each four byte chunk to make it read in right endian. Things which are 8 byte things will stay little endian but let’s not worry about that. Part 2: Write a “spray_paint” function which initializes sz bytes of the input address x to a recognizable token “tok”. void spray_paint( char *x, int sz, char tok, char *t ) { printf( "%p %3d %x %s\n", x,sz,(unsigned char) tok,t ) ; // you add the rest }x is a pointer to somewhere in the stack (the address of any automatic variable), sz is the number of bytes addresses to spray paint. x could point to anywhere. tok is a single character which will initialize x. t is a string used for debugging printout. spray_paint will also maintain two external pointers: min_ptr and max_ptr to the highest and lowest address spray painted. min_ptr will be initialized to NULL in the template. Part3: Modify the template function sub2 to 1) save the entire contents of the memory from min_ptr to max_ptr to an external array. 2) spray_paint the same area to some recognizable character, essentially destroying the entire contents of the stack. Use dumper to print it out. 3) restore the stack from the saved
