Peter Hurley 37480a0568 tty: Prevent untrappable signals from malicious program ... Commit 26df6d1340 ("tty: Add EXTPROC support for LINEMODE") allows a process which has opened a pty master to send _any_ signal to the process group of the pty slave. Although potentially exploitable by a malicious program running a setuid program on a pty slave, it's unknown if this exploit currently exists. Limit to signals actually used.
