Echo: cups: security update to 2.4.20

low Tenable Self-Hosted Container Security Plugin ID 474882

Description

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

 - OpenPrinting CUPS before 2.4.20 contains a double-free in printer-class management. When CUPS-Add-Modify-
 Class replaces an existing class member list, add_class() frees pclass->printers without clearing the
 pointer. If subsequent validation fails, the class retains the dangling pointer; CUPS-Delete-Class
 subsequently frees the same allocation in cupsdDeletePrinter(). A client authorized to modify and delete
 classes can cause scheduler-wide denial of service. The default policy requires @SYSTEM privileges.
 (CVE-2026-107886)

Solution

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