AV:L/AC:L/Au:N/C:C/I:C/A:C

An update that solves 6 vulnerabilities and has four fixes
is now available.

Description:

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

Docker was updated to 20.10.9-ce. (bsc#1191355)

See upstream changelog in the packaged
/usr/share/doc/packages/docker/CHANGELOG.md.

 CVE-2021-41092 CVE-2021-41089 CVE-2021-41091 CVE-2021-41103

container was updated to v1.4.11, to fix CVE-2021-41103. bsc#1191355

  • CVE-2021-32760: Fixed that a archive package allows chmod of file
    outside of unpack target directory (bsc#1188282)

  • Install systemd service file as well (bsc#1190826)

Update to runc v1.0.2. Upstream changelog is available from

 https://github.com/opencontainers/runc/releases/tag/v1.0.2
  • Fixed a failure to set CPU quota period in some cases on cgroup v1.
  • Fixed the inability to start a container with the “adding seccomp filter
    rule for syscall …” error, caused by redundant seccomp rules (i.e.
    those that has action equal to the default one). Such redundant rules
    are now skipped.
  • Made release builds reproducible from now on.
  • Fixed a rare debug log race in runc init, which can result in occasional
    harmful “failed to decode …” errors from runc run or exec.
  • Fixed the check in cgroup v1 systemd manager if a container needs to be
    frozen before Set, and add a setting to skip such freeze
    unconditionally. The previous fix for that issue, done in runc 1.0.1,
    was not working.

Update to runc v1.0.1. Upstream changelog is available from

https://github.com/opencontainers/runc/releases/tag/v1.0.1

  • Fixed occasional runc exec/run failure (“interrupted system call”) on an
    Azure volume.
  • Fixed “unable to find groups … token too long” error with /etc/group
    containing lines longer than 64K characters.
  • cgroup/systemd/v1: fix leaving cgroup frozen after Set if a parent
    cgroup is frozen. This is a regression in 1.0.0, not affecting runc
    itself but some
    of libcontainer users (e.g Kubernetes).
  • cgroupv2: bpf: Ignore inaccessible existing programs in case of
    permission error when handling replacement of existing bpf cgroup
    programs. This fixes a regression in 1.0.0, where some SELinux policies
    would block runc from being able to run entirely.
  • cgroup/systemd/v2: don’t freeze cgroup on Set.
  • cgroup/systemd/v1: avoid unnecessary freeze on Set.
  • fix issues with runc under openSUSE MicroOS’s SELinux policy. bsc#1187704

Update to runc v1.0.0. Upstream changelog is available from

https://github.com/opencontainers/runc/releases/tag/v1.0.0

! The usage of relative paths for mountpoints will now produce a warning
(such configurations are outside of the spec, and in future runc will
produce an error when given such configurations).

  • cgroupv2: devices: rework the filter generation to produce consistent
    results with cgroupv1, and always clobber any existing eBPF program(s)
    to fix runc update and avoid leaking eBPF programs (resulting in errors
    when managing containers).
  • cgroupv2: correctly convert “number of IOs” statistics in a
    cgroupv1-compatible way.
  • cgroupv2: support larger than 32-bit IO statistics on 32-bit
    architectures.
  • cgroupv2: wait for freeze to finish before returning from the freezing
    code, optimize the method for checking whether a cgroup is frozen.
  • cgroups/systemd: fixed “retry on dbus disconnect” logic introduced in
    rc94
  • cgroups/systemd: fixed returning “unit already exists” error from a
    systemd cgroup manager (regression in rc94)
  • cgroupv2: support SkipDevices with systemd driver
  • cgroup/systemd: return, not ignore, stop unit error from Destroy
  • Make “runc --version” output sane even when built with go get or
    otherwise outside of our build scripts.
  • cgroups: set SkipDevices during runc update (so we don’t modify cgroups
    at all during runc update).
  • cgroup1: blkio: support BFQ weights.
  • cgroupv2: set per-device io weights if BFQ IO scheduler is available.

Update to runc v1.0.0~rc95. Upstream changelog is available from
https://github.com/opencontainers/runc/releases/tag/v1.0.0-rc95

This release of runc contains a fix for CVE-2021-30465, and users are
strongly recommended to update (especially if you are providing
semi-limited access to spawn containers to untrusted users). (bsc#1185405)

Update to runc v1.0.0~rc94. Upstream changelog is available from
https://github.com/opencontainers/runc/releases/tag/v1.0.0-rc94

Breaking Changes:

  • cgroupv1: kernel memory limits are now always ignored, as kmemcg has
    been effectively deprecated by the kernel. Users should make use of
    regular memory cgroup controls.

Regression Fixes:

  • seccomp: fix 32-bit compilation errors
  • runc init: fix a hang caused by deadlock in seccomp/ebpf loading code
  • runc start: fix “chdir to cwd: permission denied” for some setups
