Someone’s just not reading the bulletins – Note the term “Remote” – including webdav, so a share that could be fully controlled by the exploiter. At least that is what I am understanding. Updates released on September 13, 2011 Microsoft Security Bulletin MS11-071, "Vulnerability in Windows Components Could Allow Remote Code Execution," provides support for vulnerable components of Microsoft Windows that are affected by the Insecure Library Loading class of vulnerabilities described in this advisory. Microsoft Security Bulletin MS11-073, "Vulnerabilities in Microsoft Office Could Allow Remote Code Execution," provides support for vulnerable components of Microsoft Office that are affected by the Insecure Library Loading class of vulnerabilities described in this advisory.
In addition, this looks like it could be ripe for abuse (if it is true): Even more interesting is the fact that you can specify a UNC path in the import section of the PE file. If we specify \\66.93.68.6\z as the name of the imported DLL, the Windows loader will try to download the DLL file from our web server. See http://www.phreedom.org/solar/code/tinype/.

This is not about placing your own DLL on a local machine so that a chosen application will load it (i.e., user "attacking" an application on his own computer).I'm not sure you understood the point. That being, whether the user knowingly or unknowingly loads the "malicious" DLL - the application will be effected the same either way. To that point: it's been possible for over a decade (and perhaps even longer) so pretending that it's some brand new threat that needs to be dealt with immediately is foolish.possibly on a remote share - and executing its code (i.e., attacker with zero privileges on user's computer executing code on that computer).Zero privileges? So having write access to a share that the user accesses/loads files from - what do you call that? This is a social engineering attack - absolutely nothing more. On a related note: have you also contacted Linus about LD_PRELOAD?

It is about an application running on your computer silently grabbing a malicious DLL from attacker-controlled location - possibly on a remote share - and executing its code (i.e., attacker with zero privileges on user's computer executing code on that computer). I hope this helps a little.

The entire "binary planting" concept was flawed from the very beginning. If you can drop a binary file on a user's machine - make it an executable and be done with it. There's nothing fancy or innovative about forcing applications to use specific DLLs - script kiddies have been doing it for over 10 years to inject custom code in multiplayer games.
