______________________________________________________________________________
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
