Description

Ignition is a utility used to manipulate systems during the initramfs. This includes partitioning disks, formatting partitions, writing files (regular files, systemd units, etc.), and configuring users. On first boot, Ignition reads its configuration from a source of truth (remote URL, network metadata service, hypervisor bridge, etc.) and applies the configuration.

The following packages have been upgraded to a later upstream version: ignition (2.14.0). (BZ#2090647)

Security Fix(es):

• ignition: configs are accessible from unprivileged containers in VMs running on VMware products (CVE-2022-1706)
