Echo: cups: security update to 2.4.20-1

low Tenable Cloud Security Plugin ID 476101

Description

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

 - OpenPrinting CUPS through 2.4.20 contains a resource-exhaustion vulnerability in the submission-timeout
 handling of cupsdCheckJobs(). The scheduler suppresses timeout processing for all pending jobs whenever
 any client connection has an in-flight Send-Document operation, without matching that connection to the
 job being examined. A client allowed to reach the IPP service can hold an incomplete HTTP request
 containing parsed Send-Document headers before operation authorization, preventing unrelated incomplete
 jobs from expiring. Where Create-Job submission is allowed, incomplete jobs can accumulate until MaxJobs
 is exhausted and further legitimate print submissions are rejected. The suppression ends when the held
 connection closes. (CVE-2026-107885)

Solution

Update the cups library and its related packages to version 2.4.20-1 or later.
