CVSS 3.0
8.8 highCVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:HCVE-2018-6553
High (8.8). EPSS 0.4% chance of exploitation in the next 30 days.
The CUPS AppArmor profile incorrectly confined the dnssd backend due to use of hard links. A local attacker could possibly use this issue to escape confinement. This flaw affects versions prior to 2.2.7-1ubuntu2.1 in Ubuntu 18.04 LTS, prior to 2.2.4-7ubuntu3.1 in Ubuntu 17.10, prior to 2.1.3-4ubuntu0.5 in Ubuntu 16.04 LTS, and prior to 1.7.2-0ubuntu1.10 in Ubuntu 14.04 LTS.
