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

medium Tenable Cloud Security Plugin ID 474771

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 caused by repeated IPP group tags in
job-creation requests. IPP parsing creates unnamed separator attributes with IPP_TAG_ZERO, but add_job()
converts these separators to IPP_TAG_JOB. During job startup, get_options()/ipp_length() subsequently
calls strlen() on a NULL attribute name, terminating cupsd and disrupting all queues. A single crafted
Print-Job request can trigger the crash when the client can reach the scheduler and submit jobs to an
accepting, enabled queue supporting the submitted document format. Anonymous submission is possible when
permitted by listener and access-control configuration. (CVE-2026-107890)

Solution

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