SUSE SLES15 Security Update : conmon, fuse-overlayfs, libcontainers-common, podman (SUSE-SU-2020:2731-1)

medium Nessus Plugin ID 143877

Language:

Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for conmon, fuse-overlayfs, libcontainers-common, podman fixes the following issues :

podman was updated to v2.0.6 (bsc#1175821)

install missing systemd units for the new Rest API (bsc#1175957) and a few man-pages that where missing before

Drop varlink API related bits (in favor of the new API)

fix install location for zsh completions

- Fixed a bug where running systemd in a container on a cgroups v1 system would fail.

- Fixed a bug where /etc/passwd could be re-created every time a container is restarted if the container's /etc/passwd did not contain an entry for the user the container was started as.

- Fixed a bug where containers without an /etc/passwd file specifying a non-root user would not start.

- Fixed a bug where the --remote flag would sometimes not make remote connections and would instead attempt to run Podman locally.

Update to v2.0.6 :

Features

- Rootless Podman will now add an entry to /etc/passwd for the user who ran Podman if run with --userns=keep-id.

- The podman system connection command has been reworked to support multiple connections, and reenabled for use!

- Podman now has a new global flag, --connection, to specify a connection to a remote Podman API instance.

Changes

- Podman's automatic systemd integration (activated by the

--systemd=true flag, set by default) will now activate for containers using /usr/local/sbin/init as their command, instead of just /usr/sbin/init and /sbin/init (and any path ending in systemd).

- Seccomp profiles specified by the --security-opt seccomp=... flag to podman create and podman run will now be honored even if the container was created using
--privileged.

Bugfixes

- Fixed a bug where the podman play kube would not honor the hostIP field for port forwarding (#5964).

- Fixed a bug where the podman generate systemd command would panic on an invalid restart policy being specified (#7271).

- Fixed a bug where the podman images command could take a very long time (several minutes) to complete when a large number of images were present.

- Fixed a bug where the podman logs command with the
--tail flag would not work properly when a large amount of output would be printed ((#7230)[https://github.com//issues/7230]).

- Fixed a bug where the podman exec command with remote Podman would not return a non-zero exit code when the exec session failed to start (e.g. invoking a non-existent command) (#6893).

- Fixed a bug where the podman load command with remote Podman would did not honor user-specified tags (#7124).

- Fixed a bug where the podman system service command, when run as a non-root user by Systemd, did not properly handle the Podman pause process and would not restart properly as a result (#7180).

- Fixed a bug where the --publish flag to podman create, podman run, and podman pod create did not properly handle a host IP of 0.0.0.0 (attempting to bind to literal 0.0.0.0, instead of all IPs on the system) (#7104).

- Fixed a bug where the podman start --attach command would not print the container's exit code when the command exited due to the container exiting.

- Fixed a bug where the podman rm command with remote Podman would not remove volumes, even if the --volumes flag was specified (#7128).

- Fixed a bug where the podman run command with remote Podman and the

--rm flag could exit before the container was fully removed.

- Fixed a bug where the --pod new:... flag to podman run and podman create would create a pod that did not share any namespaces.

- Fixed a bug where the --preserve-fds flag to podman run and podman exec could close the wrong file descriptors while trying to close user-provided descriptors after passing them into the container.

- Fixed a bug where default environment variables ($PATH and $TERM) were not set in containers when not provided by the image.

- Fixed a bug where pod infra containers were not properly unmounted after exiting.

- Fixed a bug where networks created with podman network create with an IPv6 subnet did not properly set an IPv6 default route.

- Fixed a bug where the podman save command would not work properly when its output was piped to another command (#7017).

- Fixed a bug where Podman did not clear CMD from the container image if the user overrode ENTRYPOINT (#7115).

- Fixed a bug where error parsing image names were not fully reported (part of the error message containing the exact issue was dropped).

- Fixed a bug where the podman images command with remote Podman did not support printing image tags in Go templates supplied to the --format flag (#7123).

- Fixed a bug where the podman rmi --force command would not attempt to unmount containers it was removing, which could cause a failure to remove the image.

- Fixed a bug where the podman generate systemd --new command could incorrectly quote arguments to Podman that contained whitespace, leading to nonfunctional unit files (#7285).

- Fixed a bug where the podman version command did not properly include build time and Git commit.

- Fixed a bug where running systemd in a Podman container on a system that did not use the systemd cgroup manager would fail (#6734).

- Fixed a bug where capabilities from --cap-add were not properly added when a container was started as a non-root user via --user.

- Fixed a bug where Pod infra containers were not properly cleaned up when they stopped, causing networking issues (#7103).

API

- Fixed a bug where the libpod and compat Build endpoints did not accept the application/tar content type (instead only accepting application/x-tar) (#7185).

- Fixed a bug where the libpod Exists endpoint would attempt to write a second header in some error conditions (#7197).

- Fixed a bug where compat and libpod Network Inspect and Network Remove endpoints would return a 500 instead of 404 when the requested network was not found.

- Added a versioned _ping endpoint (e.g.
http://localhost/v1.40/_ping).

- Fixed a bug where containers started through a systemd-managed instance of the REST API would be shut down when podman system service shut down due to its idle timeout (#7294).

- Added stronger parameter verification for the libpod Network Create endpoint to ensure subnet mask is a valid value.

- The Pod URL parameter to the Libpod Container List endpoint has been deprecated; the information previously gated by the Pod boolean will now be included in the response unconditionally.

Change hard requires for AppArmor to Recommends. They are not needed for runtime or with SELinux but already installed if AppArmor is used [jsc#SMO-15]

Add BuildRequires for pkg-config(libselinux) to build with SELinux support [jsc#SMO-15]

Update to v2.0.4

Fixed a bug where incorrect arguments to podman images --format could cause Podman to segfault.

Fixed a bug where podman rmi --force on an image ID with more than one name and at least one container using the image would not completely remove containers using the image (#7153).

Fixed a bug where memory usage in bytes and memory use percentage were swapped in the output of podman stats

--format=json.

Fixed a bug where the libpod and compat events endpoints would fail if no filters were specified (#7078).

Fixed a bug where the CgroupVersion field in responses from the compat Info endpoint was prefixed by 'v' (instead of just being '1' or '2', as is documented).

fix creating a directory if the destination already exists in the upper layer.

report correctly the number of links for a directory also for subsequent stat calls

stop looking up the ino in the lower layers if the file could not be opened

make sure the destination is deleted before doing a rename(2). It prevents a left over directory to cause delete to fail with EEXIST.

honor --debug.

- Add back skip_mount_home

Remove remaining difference between SLE and openSUSE package and ship the some mounts.conf default configuration on both platforms. As the sources for the mount point do not exist on openSUSE by default this config will basically have no effect on openSUSE. (jsc#SLE-12122, bsc#1175821)

Update to image 5.4.4

- Remove registries.conf VERSION 2 references from man page

- Intial authfile man page

- Add $HOME/.config/containers/certs.d to perHostCertDirPath

- Add $HOME/.config/containers/registries.conf to config path

- registries.conf.d: add stances for the registries.conf

update to libpod 1.9.3

- userns: support --userns=auto

- Switch to using --time as opposed to --timeout to better match Docker

- Add support for specifying CNI networks in podman play kube

- man pages: fix inconsistencies

Update to storage 1.19.1

- userns: add support for auto

- store: change the default user to containers

- config: honor XDG_CONFIG_HOME

Remove the /var/lib/ca-certificates/pem/SUSE.pem workaround again. It never ended up in SLES and a different way to fix the underlying problem is being worked on.

Add registry.opensuse.org as default registry [bsc#1171578]

Add /var/lib/ca-certificates/pem/SUSE.pem to the SLES mounts. This for making container-suseconnect working in the public cloud on-demand images. It needs that file for being able to verify the server certificates of the RMT servers hosted in the public cloud.
