medium Nessus Plugin ID 143322

Language:

Synopsis

The remote openSUSE host is missing a security update.

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].
