SCA: security update for glances (GHSA-v5r2-qh84-fjx5)

high Tenable Cloud Security Plugin ID 443765

Description

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

 - Glances is an open-source system cross-platform monitoring tool. Prior to 4.5.5, the Glances KVM/QEMU
 monitoring engine (glances/plugins/vms/engines/virsh.py) passes VM domain names, read directly from virsh
 list --all output, into f-string command templates that are processed by secure_popen(). secure_popen() is
 explicitly designed to interpret &&, |, and > as shell operators. Because domain names are never sanitised
 before interpolation, any user with the ability to create or rename a KVM/QEMU virtual machine can execute
 arbitrary commands as the OS user running Glances — commonly root on hypervisor hosts. This vulnerability
 is fixed in 4.5.5. (CVE-2026-46606)

Solution

Update the glances library and its related packages to version 4.5.5 or later.
