Systems running Oracle Solaris 11.3 or 11.4 where untrusted users or processes can log on, including shared hosts, jump boxes and build machines. The attacker needs a local logon, so single-user machines with no other accounts are at much lower risk, but any foothold on a Solaris host becomes a full takeover. Other operating systems are not affected.
