Описание
A flaw was found in Podman. The podman machine init command fails to verify the TLS certificate when downloading the VM images from an OCI registry. This issue results in a Man In The Middle attack.
Отчет
To exploit this flaw, a user needs to download an image from an untrusted OCI registry, specifically, an OCI registry with an invalid TLS certificate. This allows a remote attacker with access to the network path between the registry and the client to perform a Man In the Middle attack.
Меры по смягчению последствий
Download the VM image manually with another tool that verifies the TLS certificate and then pass the local image as a file path to podman, for example:
podman machine init --image
