Subject: RE: First vulnerabilities in the SP2 - XP ?...

Given that the scenario behind this presumes that the user downloads an
executable and runs it from the command line one could be just as
vulnerable running Mozilla or any other browser that allows you to
download files. Add a chmod step and other operating systems are just as
"vulnerable." 

The only remotely interesting point here is that zone information
doesn't follow the files reliably into the file system. Personally I'm
not surprised by this, and it appears that neither is Microsoft. He's
assuming behavior that isn't indicated or documented.

Where do we draw the line on this social engineering stuff? If I send an
e-mail to someone telling them to flush their iPod down the crapper does
that mean the iPod is vulnerable to a toilet attack?

Hi,

> http://www.heise.de/security/artikel/50051
I also read this yesterday (the German version) and I think it's not a
vulnerability. It's IMO a misconception in the way how SP2 treats alien
executables. And on the other hand it does not actually lower the value
of
SP2 concerning security - because the rest of SP2 already boosted
security (this time despite compatibility issues - thanks to MS for
finally skipping compatibility in favor of security). But I agree with
the author that MS should fix this anyway!

Can someone please check if ShellExecute()/ShellExecuteEx() behave
different from the CreateProcess-functions *)? Could that be the reason?
Where is the information stored, that a file was downloaded - ADS? -
EAs?
... some arcane new feature?

Oliver

*) CreateProcess, CreateProcessAsUser, CreateProcessWithLogonW,
CreateProcessWithTokenW
