Description Lubomir Kundrak 2007-12-12 14:00:23 UTC

Description of problem:

Quoting Debian bug report:
With the addition of the feature to send a message to the logged in user
when they return and unlock a locked session, this gives local attackers
the ability to read the X selection and clipboard buffers with a middle
click on the mouse and a Ctrl+V. I note that the box to leave a message
doesn't have a context menu that you could paste via, but it doesn't go
far enough.

Comment 1 Lubomir Kundrak 2007-12-15 09:58:49 UTC

CVE identifier was requested

Comment 2 Ray Strode [halfline] 2007-12-17 16:20:33 UTC

This was recently fixed upstream.

Comment 3 Ray Strode [halfline] 2007-12-17 16:23:30 UTC

ah, i'm not paying close enough attention. you've already mentioned the upstream
report.

Comment 4 Lubomir Kundrak 2007-12-17 16:29:25 UTC

Ray: Still thanks for noticing. I'd like to see this fixed by an update, but
Mitre still didn't assign a CVE. By the way, does the user have possibility to
disable the feature at all?

Comment 5 Ray Strode [halfline] 2007-12-17 16:48:07 UTC

It's a compile time thing, unfortunately.  The only way to disable it is to
rebuild without libnotify support or turn on dialog themes and load a themed
dialog that lacks the button (I think our default one lacks the button actually,
so you should be able to use it until an update goes out).

Comment 7 Lubomir Kundrak 2008-03-27 20:45:10 UTC

What's the status of fixing this in stable releases?

Comment 8 Ray Strode [halfline] 2008-03-28 13:45:45 UTC

this fell off my radar, i'll look into this today after some 5.2 work.

Comment 9 Josh Bressers 2008-05-07 18:01:35 UTC

This only affects the version of Gnome in Fedora, as the current version in
RHEL5 lacks the ability to leave a message for a user.
