    "title": "Podman: The `podman run` command can be instructed to disable almost all sandboxing by image annotation",
    "summary": "### Impact Podman v4.4.0 added a feature where container checkpoints (from the `podman container checkpoint` command) could be distributed via OCI registry, and pulled from that registry and run via the `podman run` command. This allowed easy transfer of checkpoints between systems. However, checkpoints allow complete control of how the container is created - including full control of the container sandbox. When `podman run` detects a checkpoint, it will silently ignore all user input regarding how the container should be created - for example, `podman run --cap-drop=ALL` on an image that is determined to be a checkpoint will ignore `--cap-drop=all` and use the set of capabilities specified by the checkpoint image instead, which could include all capabilities. Podman identifies checkpoint images by looking for an annotation, `io.podman.annotations.checkpoint.runtime.name`. If this annotation is set, the image is treated as a checkpoint. Conflating container images and checkpoints in `podman run` allows inherently insecure behavior as the image can now control how it is executed. The Podman Maintainers have determined that the safest course of action is to remove this functionality. ### Patch The commit introducing this functionality was reverted. 3721ff82ffb44a4ceeaecc5abd3808e924a6b669 c74b1d37b3fb834b0de43e176565d9d8c254b627 fa6cef22c2baf3987b581c673bb416ef0585daf7 (main) ea9243e04d1db3886dc3a51ee3300ffb547cfc02 450c64426dbcff1097d3c7911d791101e3d16f4c 2d05a7c61f022d4f24980",
