Comment 1 Max von Witzendorff 2012-10-10 09:39:47 EDT
I am surprised no one seems to care about this bug, since i consider it quite a security problem when a program connects to the Internet without the user knowing it. I am even more surprised that this hasn't been already fixed with the bugfix for this bug: bugzilla.redhat.com/show_bug.cgi?id=752022 How come I am expiring the same problem now again, only with a flickr server? By the way I also don't understand why this library has to be a dependency of gnome-3. For me its useless. So for anybody coming here, having the same problem as me: If you don't need this social web stuff, you can prevent it from loading with sudo chmod a-x /usr/lib/libsocialweb/services/*
Comment 2 Peter Robinson 2012-10-10 15:53:23 EDT
Security team: This is similar to RHBZ # 752022 can you please deal? Rob: You fixed a similar issue in the twitter plugin previously (https://bugzilla.redhat.com/show_bug.cgi?id=752022#c10) , I'm not sure if this is still your remit, if not can you point me to the correct person now? Max: it's not that I don't care, I've only just seen this :)

Peter: I'll fix this and spin a new release for the tarball deadline today.
Comment 7 Peter Robinson 2012-10-15 07:35:18 EDT
(In reply to comment #6) > Peter: I'll fix this and spin a new release for the tarball deadline today. Rob: thanks. Can you review all the socialweb providers to ensure we have no others with issues as well. We've had this once before with twitter so it would be good to ensure we get them all.
Comment 8 Rob Bradford 2012-10-15 08:43:07 EDT
Peter: This problem is subtly different to the pattern that affected twitter. I already fixed all the issues that matched the twitter pattern in the last point release. I would also question why this package is installed by default given that nothing on a stock F17 desktop install depends on it?
Comment 9 Peter Robinson 2012-10-15 09:24:18 EDT
> I would also question why this package is installed by default given that > nothing on a stock F17 desktop install depends on it? gnome-online-accounts links against it
Comment 10 Rob Bradford 2012-10-15 11:01:57 EDT
That's odd - when I did "yum remove libsocialweb" it didn't threaten to remove anything else (well, except libsocialweb-keys...:-) Anyway there is a 0.25.21 on the servers for you.
