Hi, I wanted to point out a recent blogpost by IT security export Chris Evans: https://scarybeastsecurity.blogspot.dk/2016/11/0day-poc-risky-design-decisions-in.html
The short version: Chrome automatically downloads files without a file dialog, tracker (part of the GNOME desktop) subsequently automatically indexes these files with a wide variety of parsers (including gstreamer, but also others like imagemagick). While the bugs that evans points out have been fixed (and the gstreamer team has fixed a whole bunch of other potential security issues I reported in the past days, thanks!), the whole design of Tracker seems incredibly risky. It is certainly worthwhile trying to make the underlying software more secure, but having tried to do that before I find it unlikely that projects like gstreamer or imagemagick will ever be in a state where we can feel comfortable feeding them with untrusted files. The core problem here is that tracker automatically parses files of potentially unknown origin with parsers that haven't been built with security in mind. This happens without any sandboxing. I think there needs to be a wider discussion about this and the fundamental design choices done here need to be questioned. -- Hanno Böck https://hboeck.de/ mail/jabber: ha...@hboeck.de GPG: FE73757FA60E4E21B937579FA5880072BBB51E42 _______________________________________________ desktop-devel-list mailing list desktop-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/desktop-devel-list
