2428d114b29a7635b37b13ee27f71b288c04d0ac2bcc0c3a7183642ad95f19a5Ubuntu Security Notice 6125-1 - It was discovered that the snap sandbox did not restrict the use of the ioctl system call with a TIOCLINUX request. This could be exploited by a malicious snap to inject commands into the controlling terminal which would then be executed outside of the snap sandbox once the snap had exited. This could allow an attacker to execute arbitrary commands outside of the confined snap sandbox. Note: graphical terminal emulators like xterm, gnome-terminal and others are not affected - this can only be exploited when snaps are run on a virtual console.
