snapd (2.58+22.04.1) jammy-security; urgency=medium
* SECURITY UPDATE: possible sandbox escape via TIOCLINUX ioctl
- interfaces/seccomp/template.go: block ioctl with TIOCLINUX. Patch
from upstream. 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.
