Security update for podman
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.
- The
- 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
-
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
andpodman 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
onADD
andCOPY
instructions has been greatly improved, especially when a.dockerignore
is present. - The
podman run
andpodman 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
andpodman 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
andpodman create
commands now feature a--sdnotify
option to control the behavior of systemd's sdnotify with containers, enabling improved support for Podman inType=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
andpodman 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 handlesHostAlias
entries. - The
podman generate kube
command now adds entries to/etc/hosts
from--host-add
generated YAML asHostAlias
entries. - The
podman play kube
andpodman generate kube
commands now properly supportshareProcessNamespace
to share the PID namespace in pods. - The
podman volume ls
command now supports thedangling
filter to identify volumes that are dangling (not attached to any container). - The
podman run
andpodman create
commands now feature a--umask
option to set the umask of the created container. - The
podman create
andpodman 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 ofpodman run
andpodman create
now supports a new mount type,type=devpts
, to add adevpts
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 topodman run
andpodman 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 topodman run
andpodman create
,--cgroup-conf
, which allows for advanced configuration of cgroups on cgroups v2 systems. - The
podman create
andpodman 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.
- A new command,
- 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. Thepodman 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 mountednoexec
, but is now unlimited size and mountedexec
. - 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].

Описание
An information disclosure vulnerability was found in containers/podman in versions before 2.0.5. When using the deprecated Varlink API or the Docker-compatible REST API, if multiple containers are created in a short duration, the environment variables from the first container will get leaked into subsequent containers. An attacker who has control over the subsequent containers could use this flaw to gain access to sensitive information stored in such variables.
