Affected: containerd

containerd is an open source container runtime. A bug was found in containerd's CRI implementation where a user can exhaust memory on the host. In the CRI stream server, a goroutine is launched to handle terminal resize events if a TTY is requested. If the user's process fails to launch due to, for example, a faulty command, the goroutine will be stuck waiting to send without a receiver, resulting in a memory leak. Kubernetes and crictl can both be configured to use containerd's CRI implementation and the stream server is used for handling container IO. This bug has been fixed in containerd 1.6.12 and 1.5.16. Users should update to these versions to resolve the issue. Users unable to upgrade should ensure that only trusted images and commands are used and that only trusted users have permissions to execute commands in running containers.

Affected: Ubuntu:18.04:LTS: containerd, Ubuntu:20.04:LTS: containerd, Ubuntu:22.04:LTS: containerd

It was discovered that containerd incorrectly handled memory when receiving certain faulty Exec or ExecSync commands. A remote attacker could possibly use this issue to cause a denial of service or crash containerd. (CVE-2022-23471, CVE-2022-31030)

It was discovered that containerd incorrectly set up inheritable file capabilities. An attacker could possibly use this issue to escalate privileges inside a container. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. (CVE-2022-24769)

It was discovered that containerd incorrectly handled access to encrypted container images when using imgcrypt library. A remote attacker could possibly use this issue to access encrypted images from other users. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. (CVE-2022-24778)
