What is CVE-2017-9780?
CVE-2017-9780 is a high-severity vulnerability in Debian Debian Linux, published on 21 Jun 2017. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
In Flatpak before 0.8.7, a third-party app repository could include malicious apps that contain files with inappropriate permissions, for example setuid or world-writable. The files are deployed with those permissions, which would let a local attacker run the setuid executable or write to the world-writable location. In the case of the "system helper" component, files deployed as part of the app are owned by root, so in the worst case they could be setuid root.
