    BuYS: Make yourself win!!!

    Alright.. this one is a bit tough coz i am gonna imply some rules on how to solve this ...

    Take the program:

    #include<stdio.h>
    main(int argc, char **argv)
    {
    int flag;
    char buffer[80];
    strcpy(buffer,argv[1]);
    if(flag==0x41414141)
    printf("you lose\n");
    }

    The point is to make this program print "you win" .. An obvious solution is to overwrite the ret address with the address of your code that prints "you win" . I dont want that.. Infact doing by *the new* way is much more simpler.. You can even try your own methods but i dont want the above solution ...

    So think different ..try hard..

    [*] To follow the path: look to the master, follow the master, walk with the master, see through the master,
    ------> become the master!!! <------
    [*] Everyone has a will to WIN but very few have the will to prepare to WIN
    [*] Invest yourself in everything you do, there's fun in being serious

    Think non-executable stack.. if u are able to defeat it..
    try getting a root shell (uid=0,gid=0) coz using this particular technique drops privileges before giving a shell.. and i wont be online for some days..sem exams so you need to wait a lil bit for my reply to ur pm's
