Echo: util-linux: security update to 2.41-5+e7

medium Tenable Cloud Security Plugin ID 457332

Description

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

 - A flaw was found in util-linux. Improper hostname canonicalization in the `login(1)` utility, when invoked
 with the `-h` option, can modify the supplied remote hostname before setting `PAM_RHOST`. A remote
 attacker could exploit this by providing a specially crafted hostname, potentially bypassing host-based
 Pluggable Authentication Modules (PAM) access control rules that rely on fully qualified domain names.
 This could lead to unauthorized access. (CVE-2026-3184)

Solution

Update the util-linux library and its related packages to version 2.41-5+e7 or later.
