Bug#903201: cinnamon: CVE-2018-13054: privilege escalation in cinnamon-settings-users.py GUI
Source: cinnamon
Version: 3.2.7-4
Severity: grave
Tags: patch security upstream
Forwarded: https://github.com/linuxmint/Cinnamon/pull/7683
Hi,
The following vulnerability was published for cinnamon.
CVE-2018-13054[0]:
| 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.
It requires admin intervention though, but still filling it as RC
severity.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
