Name of the Vulnerable Software and Affected Versions snap (affected versions not specified)

Description A malicious snap could inject contents into the input of the controlling terminal using the TIOCLINUX ioctl request, allowing it to execute arbitrary commands outside of the snap sandbox after the snap exits. This issue can only be exploited when snaps are run on a virtual console, and graphical terminal emulators like xterm and gnome-terminal are not affected.
