CVE-2018-13054
The cinnamon-settings-users.py GUI runs as root and allows configuration of (for example) other users' icon files in _on_face_browse_menuitem_activated and _on_face_menuitem_activated.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.20%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An issue was discovered in Cinnamon 1.9.2 through 3.8.6. The cinnamon-settings-users.py GUI runs as root and allows configuration of (for example) other users' icon files in _on_face_browse_menuitem_activated and _on_face_menuitem_activated. These icon files are written to the respective user's $HOME/.face location. If an unprivileged user prepares a symlink pointing to an arbitrary location, then this location will be overwritten with the icon content.
