Security update for runc
This update for runc fixes the following issues:
Update to runc v1.0.3.
- CVE-2021-43784: Fixed a potential vulnerability related to the internal usage of netlink, which is believed to not be exploitable with any released versions of runc (bsc#1193436)
- Fixed inability to start a container with read-write bind mount of a read-only fuse host mount.
- Fixed inability to start when read-only /dev in set in spec.
- Fixed not removing sub-cgroups upon container delete, when rootless cgroup v2 is used with older systemd.
- Fixed returning error from GetStats when hugetlb is unsupported (which causes excessive logging for kubernetes).

Описание
runc is a CLI tool for spawning and running containers on Linux according to the OCI specification. In runc, netlink is used internally as a serialization system for specifying the relevant container configuration to the `C` portion of the code (responsible for the based namespace setup of containers). In all versions of runc prior to 1.0.3, the encoder did not handle the possibility of an integer overflow in the 16-bit length field for the byte array attribute type, meaning that a large enough malicious byte array attribute could result in the length overflowing and the attribute contents being parsed as netlink messages for container configuration. This vulnerability requires the attacker to have some control over the configuration of the container and would allow the attacker to bypass the namespace restrictions of the container by simply adding their own netlink payload which disables all namespaces. The main users impacted are those who allow untrusted images with untrusted configurations to run on their machines (such as with shared cloud infrastructure). runc version 1.0.3 contains a fix for this bug. As a workaround, one may try disallowing untrusted namespace paths from your container. It should be noted that untrusted namespace paths would allow the attacker to disable namespace protections entirely even in the absence of this bug.
