Security update for containerd, docker, runc

This update for containerd, docker, runc fixes the following issues:

Docker was updated to 20.10.6-ce (bsc#1184768, bsc#1182947, bsc#1181594)

  • Switch version to use -ce suffix rather than _ce to avoid confusing other tools (bsc#1182476).
  • CVE-2021-21284: Fixed a potential privilege escalation when the root user in the remapped namespace has access to the host filesystem (bsc#1181732)
  • CVE-2021-21285: Fixed an issue where pulling a malformed Docker image manifest crashes the dockerd daemon (bsc#1181730).
  • btrfs quotas being removed by Docker regularly (bsc#1183855, bsc#1175081)

runc was updated to v1.0.0~rc93 (bsc#1182451, bsc#1175821 bsc#1184962).

  • Use the upstream runc package (bsc#1181641, bsc#1181677, bsc#1175821).
  • Fixed /dev/null is not available (bsc#1168481).
  • CVE-2021-30465: Fixed a symlink-exchange attack vulnarability (bsc#1185405).

containerd was updated to v1.4.4

  • CVE-2021-21334: Fixed a potential information leak through environment variables (bsc#1183397).
  • Handle a requirement from docker (bsc#1181594).

This update was imported from the SUSE:SLE-15:Update update project.

Описание

In Docker before versions 9.03.15, 20.10.3 there is a vulnerability involving the --userns-remap option in which access to remapped root allows privilege escalation to real root. When using "--userns-remap", if the root user in the remapped namespace has access to the host filesystem they can modify files under "/var/lib/docker/<remapping>" that cause writing files with extended privileges. Versions 20.10.3 and 19.03.15 contain patches that prevent privilege escalation from remapped user.

In Docker before versions 9.03.15, 20.10.3 there is a vulnerability in which pulling an intentionally malformed Docker image manifest crashes the dockerd daemon. Versions 20.10.3 and 19.03.15 contain patches that prevent the daemon from crashing.

Описание

In containerd (an industry-standard container runtime) before versions 1.3.10 and 1.4.4, containers launched through containerd's CRI implementation (through Kubernetes, crictl, or any other pod/container client that uses the containerd CRI service) that share the same image may receive incorrect environment variables, including values that are defined for other containers. If the affected containers have different security contexts, this may allow sensitive information to be unintentionally shared. If you are not using containerd's CRI implementation (through one of the mechanisms described above), you are not vulnerable to this issue. If you are not launching multiple containers or Kubernetes pods from the same image which have different environment variables, you are not vulnerable to this issue. If you are not launching multiple containers or Kubernetes pods from the same image in rapid succession, you have reduced likelihood of being vulnerable to this issue This vulnerability has been fixed in containerd 1.3.10 and containerd 1.4.4. Users should update to these versions.

Описание

runc before 1.0.0-rc95 allows a Container Filesystem Breakout via Directory Traversal. To exploit the vulnerability, an attacker must be able to create multiple containers with a fairly specific mount configuration. The problem occurs via a symlink-exchange attack that relies on a race condition.
