How to use the Apache Chunked-Encoding Hole?

I see the Apache Chunked-Encoding in securityfocus.com. it's post two exploit
http://www.securityfocus.com/bid/5033/exploit/
apache-scalp.c and apache-nosejob.c
i use it,but in the apache 1.19 Linux system is not success.

This is correct. It shouldn't work.

Code:

---

/*
 * apache-scalp.c
 * OPENBSD/X86 APACHE REMOTE EXPLOIT!!!!!!!
 *
<snip>
* Remote OpenBSD/Apache exploit for the "chunking" vulnerability.

And:

Code:

---

/*
 * apache-nosejob.c - Now with FreeBSD & NetBSD targets ;>
<snip>
struct {
        char *type;                /* description for newbie penetrator */
        int delta;                /* delta thingie! */
        u_long retaddr;                /* return address */
        int repretaddr;                /* we repeat retaddr thiz many times in the buffer */
        int repzero;                /* and \0'z this many times */
} targets[] = {        // hehe, yes theo, that say OpenBSD here!

So yes, it doesn't work on linux. Use the source luke!
