Description

Several vulnerabilities were discovered in CUPS, the Common UNIX Printing System. These issues have been identified with the following CVE ids:

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-2018-4182 Dan Bastone of Gotham Digital Science discovered that an attacker with sandboxed root access can execute backends without a sandbox profile by provoking an error in CUPS
