CVE-2017-15400
Rory McNamara discovered that an attacker is able to execute arbitrary commands (with the privilege of the CUPS daemon) by setting a malicious IPP server with a crafted PPD file.
CVE-2018-4180
Dan Bastone of Gotham Digital Science discovered that a local attacker with access to cupsctl could escalate privileges by setting an environment variable.
CVE-2018-4181
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 using an alternate name that has been hard linked to dnssd.
For the stable distribution (stretch), these problems have been fixed in version 2.2.1-8+deb9u2.
We recommend that you upgrade your cups packages.
For the detailed security status of cups please refer to its security tracker page at: [link moved to references]");
