Subject: Re: Microsoft's Binary Planting Clean-Up Mission

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.

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.

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?

Hi Adam,

I'm afraid you don't fully understand the issue. 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). 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.

Cheers,
Mitja
