Summary
snapd vulnerability
Details
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.
