Description Florian Schuhmacher 2018-07-03 05:14:17 UTC
An issue was discovered in Cinnamon 1.9.2 through 3.8.6. The 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.

Looks like the fix was in-tree by upstream version 4.2.0:

We're at 4.4.8, so I guess we're good here? Tree is clean, if so:

Yeah, Bug 704532 bumped cinnamon to 4.4 and the vulnerable versions were removed by Bug 720190.

Though it looks like the 4.2.0 change simply fixed the ability to edit the .face file which was broken by the original security fix.
