runc rc95 contains a fix for CVE-2021-30465. runc rc94 provides fixes and improvements. One notable change is cgroup manager's Set now accept Resources rather than Cgroup (see https://github.com/opencontainers/runc/pull/2906). Modify the code accordingly. Also update runc dependencies (as hinted by hack/lint-depdendencies.sh): github.com/cilium/ebpf v0.5.0 github.com/containerd/console v1.0.2 github.com/coreos/go-systemd/v22 v22.3.1 github.com/godbus/dbus/v5 v5.0.4 github.com/moby/sys/mountinfo v0.4.1 golang.org/x/sys v0.0.0-20210426230700-d19ff857e887 github.com/google/go-cmp v0.5.4 github.com/kr/pretty v0.2.1 github.com/opencontainers/runtime-spec v1.0.3-0.20210326190908-1c3f411f0417 Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
