containerd: Unpack DoS via repeated opaque whiteouts
影響: go:github.com/containerd/containerd/v2 < 2.0.12 → 2.0.12, go:github.com/containerd/containerd < 1.7.35 → 1.7.35, go:github.com/containerd/containerd/v2 >= 2.2.0, < 2.2.8 → 2.2.8, go:github.com/containerd/containerd/v2 >= 2.3.0, < 2.3.5 → 2.3.5 A vulnerability exists in containerd's layer unpack handler where the processing of certain image layers causes superlinear time complexity. During the unpack operation, specific file configurations within the layer can trigger repeated directory traversals. Consequently, pulling or importing a maliciously crafted image can result in increased unpack times and a moderate increase in CPU usage. This delays container startup, even if the compressed image layers are small. Additionally, in…
containerd CRI plugin: Checkpoint restore bypasses destination security context
影響: go:github.com/containerd/containerd/v2 >= 2.1.0, < 2.2.7 → 2.2.7, go:github.com/containerd/containerd/v2 >= 2.3.0, < 2.3.4 → 2.3.4 A vulnerability in containerd's CRI implementation allows a container restored from an untrusted checkpoint via the CreateContainer API to bypass the destination security context and execute with elevated privileges. When restoring a container from a checkpoint archive or annotated OCI image, CRIU restores process credentials, Linux capabilities, no_new_privs, and seccomp state directly from checkpoint data rather than enforcing the destination CRI ContainerConfig. An attacker who can ru…
