It was discovered that there was a symlink attack in the Cinnamon desktop environment.

An attacker could overwrite an arbitrary file on the filesystem via a $HOME/.face icon file (as the cinnamon-settings-users.py GUI runs as root).

For Debian 8 ‘Jessie’, this issue has been fixed in cinnamon version 2.2.16-5+deb8u1.

We recommend that you upgrade your cinnamon packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
