CVSS: 5.9EPSS: 0%CPEs: 4EXPL: 0CVE-2020-11934 – Sandbox escape vulnerability via snapctl user-open (xdg-open)
https://notcve.org/view.php?id=CVE-2020-11934
It was discovered that snapctl user-open allowed altering the $XDG_DATA_DIRS environment variable when calling the system xdg-open. OpenURL() in usersession/userd/launcher.go would alter $XDG_DATA_DIRS to append a path to a directory controlled by the calling snap. A malicious snap could exploit this to bypass intended access restrictions to control how the host system xdg-open script opens the URL and, for example, execute a script shipped with the snap without confinement. This issue did not affect Ubuntu Core systems. Fixed in snapd versions 2.45.1ubuntu0.2, 2.45.1+18.04.2 and 2.45.1+20.04.2. • https://launchpad.net/bugs/1880085 https://ubuntu.com/USN-4424-1 • CWE-668: Exposure of Resource to Wrong Sphere •
