CVE-2017-18248
The add_job function in scheduler/ipp.c in CUPS before 2.2.6, when D-Bus support is enabled, can be crashed by remote attackers by sending print jobs with an invalid username, related to a D-Bus notification.
Does this matter?
Lower severity and a low EPSS score (2.20%). Track it; it rarely justifies an emergency change on its own.
