Thanks for your interest and response but I don't see how this
addresses my point - I've checked the links (of which only one appears
to refer Facebook ActiveX vulnerability).
I already knew that it was a buffer overflow in the ActiveX control
but I don't know what tirggers the overflow
1. A malicious Download agent on the Server
or
2. A crafted image file
or
3. something else
If it is the first two then I'm not so worried - because I doubt that
Facebook (assuming I'm not misdirected) would attack me with a
malicious agent and I'm also confident of the sources of any images I
care to upload (i.e. they will come from my camera).
If it is '3' (something else) then maybe I should be worried - but I
have not got an answer to that.
Does anyone have such an answer?
Thanks
