There seems to have been a problem in propagating the CVE assigned though, so we apologies for that. The assigned CVE is not mentioned in the NEWS, but see below for the fixing commit. Luke Faraone <lfaraone@...ian.org>: > SYNOPSIS: > Double-clicking a file in the user's media library with > a specially-crafted path or filename allows for > arbitrary code execution with the permissions of the > user running Pitivi. > > STEPS TO REPRODUCE: > 1. Create a directory hierarchy like so: > "images/$(xeyes)/", and place an image "hello.png" in > "images/$(xeyes)/". > 2. Drag and drop "images" to the Pitivi media library. > 3. Double click the image "hello.png" in the media library > > The `xeyes` program (if installed on your system) should start. > > See pitivi/mainwindow.py:_mediaLibraryPlayCb(). > > An exploit scenario would require an attacker to provide a > specially-crafted directory hierarchy or file path. Since Pitivi does > not expose the path to the user, and a workflow of consuming content > created by others is common when working with media files, such a > scenario occurring is not hard to imagine. This issue was fixed upstream in 0.95 with commit 45a4c84edb3b4343f199bba1c65502e3f49f5bb2.  http://www.pitivi.org/  https://git.gnome.org/browse/pitivi/commit/?id=45a4c84edb3b4343f199bba1c65502e3f49f5bb2 Regards, Salvatore
