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

medium Tenable Cloud Security Plugin ID 474864

Description

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

 - OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. Prior
 to 2.4.20, copy_banner() in scheduler/ipp.c uses the attacker-controlled IPP attributes-natural-language
 value as a directory component beneath DataDir/banners when processing a job-sheets banner. The job-sheets
 value must first match a registered banner basename, and the traversed path must contain a matching
 reachable basename; selecting an arbitrary target as demonstrated additionally requires pre-positioned
 path state such as a symlink with that basename. Subject to the scheduler's filesystem and sandbox access,
 path separators in the language value can escape the intended banner directory, make the root scheduler
 open the reachable file, and copy its bytes into a job-sheet spool object that a configured backend can
 deliver to an attacker-observable endpoint. This issue is fixed in version 2.4.20. (CVE-2026-61702)

Solution

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