Package: mat Version: 0.6.1-3 Severity: important Hi,
I found this bug while working the upcoming version of Tails based on Stretch but I could also reproduce it in Debian Stretch. MAT can be used through 2 different paths from the standalone GUI or from the contextual menu in Nautilus. This bug affects the contextual menu in Nautilus. Steps to reproduce in GNOME: * Open MAT. * Press the *PrintScreen* key to take a screenshot. * Navigate to ~/Pictures. * Drag and drop the screenshot in MAT. * The screenshot is marked as **Dirty** in MAT (as expected) as the metadata of the file include "Software: gnome-screenshot". * Right-click on the screenshot in Nautilus and choose **Clean metadata**. * Result: I got no feedback (while in previous version a backup copy was created which provided visual feedback about the success of the operation). * Drag and drop again the screen in MAT. * The screenshot is still marked as **Dirty** in MAT and still has the "Software: gnome-screenshot". That's the bug. * Click on the screenshot in MAT to select it. Click on the **Clean** button and the screenshot gets marked as **Clean** (as expected). I'm flagging this as "important" for the time being but I think that it's a serious security issue since people might got use to clean metadata from backup file in comparison with the version in Jessie. So, in my opinion, and if I understood correctly, this renders MAT useless for probably most of its actual uses. -- System Information: Debian Release: 9.0 APT prefers testing APT policy: (990, 'testing') Architecture: 1489780924 WARNING torsocks[11141]: [syscall] Unsupported syscall number 217.
