CVE-2017-5226
When executing a program via the bubblewrap sandbox, the nonpriv session can escape to the parent session by using the TIOCSTI ioctl to push characters into the terminal's input buffer, allowing an attacker to escape the sandbox.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.17%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
