Podman Improper Certificate Validation; machine missing TLS verification
### Impact The podman machine init command fails to verify the TLS certificate when downloading the VM images from an OCI registry (which it does by default since 5.0.0) allowing a possible Man In The Middle attack. ### Patches https://github.com/containers/podman/commit/726b506acc8a00d99f1a3a1357ecf619a1f798c3 Fixed in v5.5.2 ### Workarounds Download the disk image manually via some other tool that verifies the TLS connection. Then pass the local image as file path (podman machine init --image ./somepath)
