Synopsis

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

Description

This update for podman fixes the following issues :

Security issue fixed :

This release resolves CVE-2020-14370, in which environment variables could be leaked between containers created using the Varlink API (bsc#1176804).

Non-security issues fixed :

add dependency to timezone package or podman fails to build a container (bsc#1178122)

Install new auto-update system units

Update to v2.1.1 (bsc#1178392) :

 - Changes

 - The `podman info` command now includes the cgroup manager Podman is using.

 - API

 - The REST API now includes a Server header in all responses.

 - Fixed a bug where the Libpod and Compat Attach endpoints could terminate early, before sending all output from the container.

 - Fixed a bug where the Compat Create endpoint for containers did not properly handle the Interactive parameter.

 - Fixed a bug where the Compat Kill endpoint for containers could continue to run after a fatal error.

 - Fixed a bug where the Limit parameter of the Compat List endpoint for Containers did not properly handle a limit of 0 (returning nothing, instead of all containers) [#7722].

 - The Libpod Stats endpoint for containers is being deprecated and will be replaced by a similar endpoint with additional features in a future release.

Changes in v2.1.0

 - Features

 - A new command, `podman image mount`, has been added.
 This allows for an image to be mounted, read-only, to inspect its contents without creating a container from it [#1433].

 - The `podman save` and `podman load` commands can now create and load archives containing multiple images [#2669].

 - Rootless Podman now supports all `podman network` commands, and rootless containers can now be joined to networks.

 - The performance of `podman build` on `ADD` and `COPY` instructions has been greatly improved, especially when a `.dockerignore` is present.

 - The `podman run` and `podman create` commands now support a new mode for the `--cgroups` option, `--cgroups=split`. Podman will create two cgroups under the cgroup it was launched in, one for the container and one for Conmon. This mode is useful for running Podman in a systemd unit, as it ensures that all processes are retained in systemd's cgroup hierarchy [#6400].

 - The `podman run` and `podman create` commands can now specify options to slirp4netns by using the `--network` option as follows :

`--net slirp4netns:opt1,opt2`. This allows for, among other things,

switching the port forwarder used by slirp4netns away from rootlessport.

 - The `podman ps` command now features a new option, `--storage`, to show containers from Buildah, CRI-O and other applications.

 - The `podman run` and `podman create` commands now feature a `--sdnotify` option to control the behavior of systemd's sdnotify with containers, enabling improved support for Podman in `Type=notify` units.

 - The `podman run` command now features a `--preserve-fds` opton to pass file descriptors from the host into the container

[#6458].

 - The `podman run` and `podman create` commands can now create overlay volume mounts, by adding the `:O` option to a bind mount

(e.g. `-v /test:/test:O`). Overlay volume mounts will mount a directory

into a container from the host and allow changes to it, but not write

those changes back to the directory on the host.

 - The `podman play kube` command now supports the Socket HostPath type [#7112].

 - The `podman play kube` command now supports read-only mounts.

 - The `podman play kube` command now supports setting labels on pods from Kubernetes metadata labels.

 - The `podman play kube` command now supports setting container restart policy [#7656].

 - The `podman play kube` command now properly handles `HostAlias` entries.

 - The `podman generate kube` command now adds entries to `/etc/hosts` from `--host-add` generated YAML as `HostAlias` entries.

 - The `podman play kube` and `podman generate kube` commands now properly support `shareProcessNamespace` to share the PID namespace in pods.

 - The `podman volume ls` command now supports the `dangling` filter to identify volumes that are dangling (not attached to any container).

 - The `podman run` and `podman create` commands now feature a `--umask` option to set the umask of the created container.

 - The `podman create` and `podman run` commands now feature a `--tz` option to set the timezone within the container [#5128].

 - Environment variables for Podman can now be added in the `containers.conf` configuration file.

 - The `--mount` option of `podman run` and `podman create` now supports a new mount type, `type=devpts`, to add a `devpts` mount to the container. This is useful for containers that want to mount `/dev/` from the host into the container, but still create a terminal.

 - The `--security-opt` flag to `podman run` and `podman create` now supports a new option, `proc-opts`, to specify options for the container's `/proc` filesystem.

 - Podman with the `crun` OCI runtime now supports a new option to `podman run` and `podman create`, `--cgroup-conf`, which allows for advanced configuration of cgroups on cgroups v2 systems.

 - The `podman create` and `podman run` commands now support a `--override-variant` option, to override the architecture variant of the image that will be pulled and ran.

 - A new global option has been added to Podman, `--runtime-flags`, which allows for setting flags to use when the OCI runtime is called.

 - The `podman manifest add` command now supports the `--cert-dir`, `--auth-file`, `--creds`, and `--tls-verify` options.

 - Security

 - This release resolves CVE-2020-14370, in which environment variables could be leaked between containers created using the Varlink API.

 - Changes

 - Podman will now retry pulling an image 3 times if a pull fails due to network errors.

 - The `podman exec` command would previously print error messages (e.g. `exec session exited with non-zero exit code

 -1`) when the command run exited with a non-0 exit code.
 It no

longer does this. The `podman exec` command will still exit with the same

exit code as the command run in the container did.

 - Error messages when creating a container or pod with a name that is already in use have been improved.

 - For read-only containers running systemd init, Podman creates a tmpfs filesystem at `/run`. This was previously limited to 65k in size and mounted `noexec`, but is now unlimited size and mounted `exec`.

 - The `podman system reset` command no longer removes configuration files for rootless Podman.

 - API

 - The Libpod API version has been bumped to v2.0.0 due to a breaking change in the Image List API.

 - Docker-compatible Volume Endpoints (Create, Inspect, List, Remove, Prune) are now available!

 - Added an endpoint for generating systemd unit files for containers.

 - The `last` parameter to the Libpod container list endpoint now has an alias, `limit` [#6413].

 - The Libpod image list API new returns timestamps in Unix format, as integer, as opposed to as strings

 - The Compat Inspect endpoint for containers now includes port information in NetworkSettings.

 - The Compat List endpoint for images now features limited support for the (deprecated) `filter` query parameter [#6797].

 - Fixed a bug where the Compat Create endpoint for containers was not correctly handling bind mounts.

 - Fixed a bug where the Compat Create endpoint for containers would not return a 404 when the requested image was not present.

 - Fixed a bug where the Compat Create endpoint for containers did not properly handle Entrypoint and Command from images.

 - Fixed a bug where name history information was not properly added in the Libpod Image List endpoint.

 - Fixed a bug where the Libpod image search endpoint improperly populated the Description field of responses.

 - Added a `noTrunc` option to the Libpod image search endpoint.

 - Fixed a bug where the Pod List API would return null, instead of an empty array, when no pods were present [#7392].

 - Fixed a bug where endpoints that hijacked would do perform the hijack too early, before being ready to send and receive data [#7195].

 - Fixed a bug where Pod endpoints that can operate on multiple containers at once (e.g. Kill, Pause, Unpause, Stop) would not forward errors from individual containers that failed.

 - The Compat List endpoint for networks now supports filtering results [#7462].

 - Fixed a bug where the Top endpoint for pods would return both a 500 and 404 when run on a non-existent pod.

 - Fixed a bug where Pull endpoints did not stream progress back to the client.

 - The Version endpoints (Libpod and Compat) now provide version in a format compatible with Docker.

 - All non-hijacking responses to API requests should not include headers with the version of the server.

 - Fixed a bug where Libpod and Compat Events endpoints did not send response headers until the first event occurred [#7263].

 - Fixed a bug where the Build endpoints (Compat and Libpod) did not stream progress to the client.

 - Fixed a bug where the Stats endpoints (Compat and Libpod) did not properly handle clients disconnecting.

 - Fixed a bug where the Ignore parameter to the Libpod Stop endpoint was not performing properly.

 - Fixed a bug where the Compat Logs endpoint for containers did not stream its output in the correct format [#7196].

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
