Echo: cups: security update to 2.4.18-1+e4

medium Tenable Cloud Security Plugin ID 474869

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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.
 (CVE-2026-107888)

Solution

Update the cups library and its related packages to version 2.4.18-1+e4 or later.
