CVE-2018-4180

 attacker with access to cupsctl could escalate privileges by setting
 an environment variable.

 Eric Rafaloff and John Dunlap of Gotham Digital Science discovered
 that a local attacker can perform limited reads of arbitrary files
 as root by manipulating cupsd.conf.

CVE-2018-6553

Dan Bastone of Gotham Digital Science discovered that an attacker
can bypass the AppArmor cupsd sandbox by invoking the dnssd backend
