Changing the search path for DLLs would break a good portion of windows
apps, especially legacy apps.
In my previous life as a windows programmer, often the trick
to get some
older apps working was to find the older version of some DLL
that it was
looking for and put it in the same directory as the
application so it would
load those ones instead of whatever twisted version now exists in the
Thus I think we will be forced to live with this security hole
though the OS
should be patched so that it never loads DLLs across network
devices or at
least obeys the security settings of the machine.
Funny that I've known this for a very long time but never thought about
using it to load trojan DLLs.
