OpenPrinting CUPS before 2.4.20 contains a NULL pointer dereference in cupsdCheckJobs() when a job marked job-held-on-create refers to a temporary printer that has been automatically deleted. Temporary-printer cleanup can remove the destination without canceling its held jobs, and the scheduler dereferences the NULL result of cupsdFindDest() while checking holding_new_jobs. This terminates cupsd and interrupts all queues managed by that process. In some plausible scenarios, an unprivileged submission can trigger this.
