    [network] Avoid out ouf bounds read in __libc_res_nquerydomain

    2012-02-28  Jeff Law  <law@redhat.com>

        * resolv/res_query.c (__libc_res_nquerydomain): Avoid
        out of bounds read.

~~~

Start with something like this:
~~~
#include <stdlib.h>
#include <resolv.h>
main()
{
 char buf[20];
 res_state statp = malloc (sizeof (res_state));
 memset (statp, 0, sizeof (statp));
 res_nquerydomain (statp, "", NULL, 0, 0, buf, 20);
}
~~~

Notes:
* mmap a page, touch first bit.
* try to get code to touch space outside of that first page.
