Description Andrej Nemec 2017-09-12 12:08:14 UTC 
Nautilus trusts desktop files that have the executable bit set, and doesn't replace the displayed icon or the displayed name until it's trusted, which prevents from running random programs by a malicious desktop file.

However, the executable permission is preserved if the desktop file comes from a compressed file. A maliciously crafted file opened by the user could result in code execution.
