- ---------------------------------
What is the impact of this vulnerability?
- ----------------------------------------
(For example: local user can gain root/privileged access, intruders
can create root-owned files, denial of service attack, etc.)
a) What is the specific impact: Users running MS NetMeeting Version 2.1
(The one that comes
with windows 98) software in a conference can copy/paste the remote
clipboard area.
b) How would you envision it being used in an attack scenario:
With the chat windows OPENED just do a CTRL-C in the box where you
write with nothing in your box and nothing selected at all. then, you
can get
the entire clipboard from the other user in the conference, of
course,
if there's something in his Clipboard (ASCII, Bin, etc).
