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' profile creation.

CVE-2018-4183

Dan Bastone and Eric Rafaloff of Gotham Digital Science discovered that an attacker with sandboxed root access can execute arbitrary commands as unsandboxed root by modifying /etc/cups/cups-files.conf

CVE-2018-6553
