Summary

A path traversal vulnerability has been discovered in podman before version 1.4.0 in the way it handles symlinks inside containers. An attacker who has compromised an existing container can cause arbitrary files on the host filesystem to be read/written when an administrator tries to copy a file from/to the container.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Relative Path Traversal
    An attacker exploits a weakness in input validation on the target by supplying a specially constructed path utilizing dot and slash characters for the purpose of obtaining access to arbitrary files or resources. An attacker modifies a known path on the target in order to reach material that is not available through intended channels. These attacks normally involve adding additional path separators (/ or \) and/or dots (.), or encodings thereof, in various combinations in order to reach parent directories or entirely separate trees of the target's directory structure.
  • Directory Traversal
    An attacker with access to file system resources, either directly or via application logic, will use various file path specification or navigation mechanisms such as ".." in path strings and absolute paths to extend their range of access to inappropriate areas of the file system. The attacker attempts to either explore the file system for recon purposes or access directories and files that are intended to be restricted from their access. Exploring the file system can be achieved through constructing paths presented to directory listing programs, such as "ls" and 'dir', or through specially crafted programs that attempt to explore the file system. The attacker engaging in this type of activity is searching for information that can be used later in a more exploitive attack. Access to restricted directories or files can be achieved through modification of path references utilized by system applications.
  • File System Function Injection, Content Based
    An attack of this type exploits the host's trust in executing remote content including binary files. The files are poisoned with a malicious payload (targeting the file systems accessible by the target software) by the attacker and may be passed through standard channels such as via email, and standard web content like PDF and multimedia files. The attacker exploits known vulnerabilities or handling routines in the target processes. Vulnerabilities of this type have been found in a wide variety of commercial applications from Microsoft Office to Adobe Acrobat and Apple Safari web browser. When the attacker knows the standard handling routines and can identify vulnerabilities and entry points they can be exploited by otherwise seemingly normal content. Once the attack is executed, the attackers' program can access relative directories such as C:\Program Files or other standard system directories to launch further attacks. In a worst case scenario, these programs are combined with other propagation logic and work as a virus.
  • Using Slashes and URL Encoding Combined to Bypass Validation Logic
    This attack targets the encoding of the URL combined with the encoding of the slash characters. An attacker can take advantage of the multiple way of encoding an URL and abuse the interpretation of the URL. An URL may contain special character that need special syntax handling in order to be interpreted. Special characters are represented using a percentage character followed by two digits representing the octet code of the original character (%HEX-CODE). For instance US-ASCII space character would be represented with %20. This is often referred as escaped ending or percent-encoding. Since the server decodes the URL from the requests, it may restrict the access to some URL paths by validating and filtering out the URL requests it received. An attacker will try to craft an URL with a sequence of special characters which once interpreted by the server will be equivalent to a forbidden URL. It can be difficult to protect against this attack since the URL can contain other format of encoding such as UTF-8 encoding, Unicode-encoding, etc.
  • Manipulating Input to File System Calls
    An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.

Additional changes by SUSE on top :

Remove fuse-overlayfs because it's (currently) an unsatisfied
dependency on SLE (bsc#1143386)

Update libpod.conf to use correct infra_command

Update libpod.conf to use better versioned pause container

Update libpod.conf to use official kubic pause container

Update libpod.conf to match latest features set: detach_keys,
lock_type, runtime_supports_json

Add podman-remote varlink client

Version update podman to v1.4.4: Features

  - Podman now has greatly improved support for containers
    using multiple OCI runtimes. Containers now remember if
    they were created with a different runtime using
    --runtime and will always use that runtime

  - The cached and delegated options for volume mounts are
    now allowed for Docker compatability (#3340)

  - The podman diff command now supports the --latest flag
    Bugfixes

  - Fixed a bug where rootless Podman would attempt to use
    the entire root configuration if no rootless
    configuration was present for the user, breaking
    rootless Podman for new installations

  - Fixed a bug where rootless Podman's pause process would
    block SIGTERM, preventing graceful system shutdown and
    hanging until the system's init send SIGKILL

  - Fixed a bug where running Podman as root with sudo -E
    would not work after running rootless Podman at least
    once

  - Fixed a bug where options for tmpfs volumes added with
    the --tmpfs flag were being ignored

  - Fixed a bug where images with no layers could not
    properly be displayed and removed by Podman

  - Fixed a bug where locks were not properly freed on
    failure to create a container or pod

  - Fixed a bug where podman cp on a single file would
    create a directory at the target and place the file in
    it (#3384)

  - Fixed a bug where podman inspect --format '{{.Mounts}}'
    would print a hexadecimal address instead of a
    container's mounts

  - Fixed a bug where rootless Podman would not add an entry
    to container's /etc/hosts files for their own hostname
    (#3405)

  - Fixed a bug where podman ps --sync would segfault
    (#3411)

  - Fixed a bug where podman generate kube would produce an
    invalid ports configuration (#3408) Misc

  - Updated containers/storage to v1.12.13

  - Podman now performs much better on systems with heavy
    I/O load

  - The --cgroup-manager flag to podman now shows the
    correct default setting in help if the default was
    overridden by libpod.conf

  - For backwards compatability, setting
    --log-driver=json-file in podman run is now supported as
    an alias for --log-driver=k8s-file. This is considered
    deprecated, and json-file will be moved to a new
    implementation in the future
    ([#3363](https://github.com/containers/libpo\
    d/issues/3363))

  - Podman's default libpod.conf file now allows the crun
    OCI runtime to be used if it is installed

Update podman to v1.4.2: Fixed a bug where Podman could not run
containers using an older version of Systemd as init

Updated vendored Buildah to v1.9.0 to resolve a critical bug with
Dockerfile RUN instructions

The error message for running podman kill on containers that are not
running has been improved

Podman remote client can now log to a file if syslog is not available

The podman exec command now sets its error code differently based on
whether the container does not exist, and the command in the container
does not exist

The podman inspect command on containers now outputs Mounts JSON that
matches that of docker inspect, only including user-specified volumes
and differentiating bind mounts and named volumes

The podman inspect command now reports the path to a container's OCI
spec with the OCIConfigPath key (only included when the container is
initialized or running)

The podman run --mount command now supports the bind-nonrecursive
option for bind mounts

Fixed a bug where podman play kube would fail to create containers due
to an unspecified log driver

Fixed a bug where Podman would fail to build with musl libc

Fixed a bug where rootless Podman using slirp4netns networking in an
environment with no nameservers on the host other than localhost would
result in nonfunctional networking

Fixed a bug where podman import would not properly set environment
variables, discarding their values and retaining only keys

Fixed a bug where Podman would fail to run when built with Apparmor
support but run on systems without the Apparmor kernel module loaded

Remote Podman will now default the username it uses to log in to
remote systems to the username of the current user

Podman now uses JSON logging with OCI runtimes that support it,
allowing for better error reporting

Updated vendored containers/image to v2.0

Update conmon to v0.3.0

Support OOM Monitor under cgroup V2

Add config binary and make target for configuring conmon with a go
library for importing values

Fixed a bug where specifying a bing mount or tmpfs mount over an image
volume would cause a container to be unable to start

Fixed a bug where podman generate kube did not work with containers
with named volumes

Fixed a bug where rootless podman would receive permission denied
errors accessing conmon.pid

Fixed a bug where podman cp with a folder specified as target would
replace the folder, as opposed to copying into it

created volumes when they were automatically removed

Fixed a bug where container and pod locks were incorrectly marked as
released after a system reboot, causing errors on container and pod
removal

Fixed a bug where Podman pods could not be removed if any container in
the pod encountered an error during removal

would encounter a race condition during removal, potentially failing
to remove the pod CGroup

Fixed a bug where the podman container checkpoint and podman container
restore commands were not visible in the remote client

"This is a version update for podman to version 1.4.4 (bsc#1143386).

Additional changes by SUSE on top :

  - Remove fuse-overlayfs because it's (currently) an
    unsatisfied dependency on SLE (bsc#1143386)

  - Update libpod.conf to use correct infra_command

  - Update libpod.conf to use better versioned pause
    container

  - Update libpod.conf to use official kubic pause container

  - Update libpod.conf to match latest features set:
    detach_keys, lock_type, runtime_supports_json

  - Add podman-remote varlink client

Version update podman to v1.4.4 :

  - Features

  - Podman now has greatly improved support for containers
    using multiple OCI runtimes. Containers now remember if
    they were created with a different runtime using
    --runtime and will always use that runtime

  - The cached and delegated options for volume mounts are
    now allowed for Docker compatability (#3340)

  - The podman diff command now supports the --latest flag

  - Bugfixes

  - Fixed a bug where rootless Podman would attempt to use
    the entire root configuration if no rootless
    configuration was present for the user, breaking
    rootless Podman for new installations

  - Fixed a bug where rootless Podman's pause process would
    block SIGTERM, preventing graceful system shutdown and
    hanging until the system's init send SIGKILL

  - Fixed a bug where running Podman as root with sudo -E
    would not work after running rootless Podman at least
    once

  - Fixed a bug where options for tmpfs volumes added with
    the --tmpfs flag were being ignored

  - Fixed a bug where images with no layers could not
    properly be displayed and removed by Podman

  - Fixed a bug where locks were not properly freed on
    failure to create a container or pod

  - Fixed a bug where podman cp on a single file would
    create a directory at the target and place the file in
    it (#3384)

  - Fixed a bug where podman inspect --format '((.Mounts))'
    would print a hexadecimal address instead of a
    container's mounts

  - Fixed a bug where rootless Podman would not add an entry
    to container's /etc/hosts files for their own hostname
    (#3405)

  - Fixed a bug where podman ps --sync would segfault
    (#3411)

  - Fixed a bug where podman generate kube would produce an
    invalid ports configuration (#3408)

  - Misc

  - Updated containers/storage to v1.12.13

  - Podman now performs much better on systems with heavy
    I/O load

  - The --cgroup-manager flag to podman now shows the
    correct default setting in help if the default was
    overridden by libpod.conf

  - For backwards compatability, setting
    --log-driver=json-file in podman run is now supported as
    an alias for --log-driver=k8s-file. This is considered
    deprecated, and json-file will be moved to a new
    implementation in the future
    ([#3363](https://github.com/containers/libpo\
    d/issues/3363))

  - Podman's default libpod.conf file now allows the crun
    OCI runtime to be used if it is installed

Update podman to v1.4.2 :

  - Fixed a bug where Podman could not run containers using
    an older version of Systemd as init

  - Updated vendored Buildah to v1.9.0 to resolve a critical
    bug with Dockerfile RUN instructions

  - The error message for running podman kill on containers
    that are not running has been improved

  - Podman remote client can now log to a file if syslog is
    not available

  - The podman exec command now sets its error code
    differently based on whether the container does not
    exist, and the command in the container does not exist

  - The podman inspect command on containers now outputs
    Mounts JSON that matches that of docker inspect, only
    including user-specified volumes and differentiating
    bind mounts and named volumes

  - The podman inspect command now reports the path to a
    container's OCI spec with the OCIConfigPath key (only
    included when the container is initialized or running)

  - The podman run --mount command now supports the
    bind-nonrecursive option for bind mounts

  - Fixed a bug where podman play kube would fail to create
    containers due to an unspecified log driver

  - Fixed a bug where Podman would fail to build with musl
    libc

  - Fixed a bug where rootless Podman using slirp4netns
    networking in an environment with no nameservers on the
    host other than localhost would result in nonfunctional
    networking

  - Fixed a bug where podman import would not properly set
    environment variables, discarding their values and
    retaining only keys

  - Fixed a bug where Podman would fail to run when built
    with Apparmor support but run on systems without the
    Apparmor kernel module loaded

  - Remote Podman will now default the username it uses to
    log in to remote systems to the username of the current
    user

  - Podman now uses JSON logging with OCI runtimes that
    support it, allowing for better error reporting

  - Updated vendored containers/image to v2.0

  - Update conmon to v0.3.0

  - Support OOM Monitor under cgroup V2

  - Add config binary and make target for configuring conmon
    with a go library for importing values

Updated podman to version 1.4.0 (bsc#1137860) and (bsc#1135460) 

  - Podman checkpoint and podman restore commands can now be
    used to migrate containers between Podman installations
    on different systems.

  - The podman cp now supports pause flag.

  - The remote client now supports a configuration file for
    pre-configuring connections to remote Podman
    installations

  - CVE-2019-10152: Fixed an iproper dereference of symlinks
    of the the podman cp command which introduced in version
    1.1.0 (bsc#1136974).

  - Fixed a bug where podman commit could improperly set
    environment variables that contained = characters

  - Fixed a bug where rootless podman would sometimes fail
    to start containers with forwarded ports

  - Fixed a bug where podman version on the remote client
    could segfault

  - Fixed a bug where podman container runlabel would use
    /proc/self/exe instead of the path of the Podman command
    when printing the command being executed

  - Fixed a bug where filtering images by label did not work

  - Fixed a bug where specifying a bing mount or tmpfs mount
    over an image volume would cause a container to be
    unable to start

  - Fixed a bug where podman generate kube did not work with
    containers with named volumes

  - Fixed a bug where rootless podman would receive
    permission denied errors accessing conmon.pid

  - Fixed a bug where podman cp with a folder specified as
    target would replace the folder, as opposed to copying
    into it

  - Fixed a bug where rootless Podman commands could
    double-unlock a lock, causing a crash

  - Fixed a bug where podman incorrectly set tmpcopyup on
    /dev/ mounts, causing errors when using the Kata
    containers runtime

  - Fixed a bug where podman exec would fail on older
    kernels

  - Podman commit command is now usable with the Podman
    remote client

  - Signature-policy flag has been deprecated

  - Updated vendored containers/storage and containers/image
    libraries with numerous bugfixes

  - Updated vendored Buildah to v1.8.3

  - Podman now requires Conmon v0.2.0

  - The podman cp command is now aliased as podman container
    cp

  - Rootless podman will now default init_path using root
    Podman's configuration files
    (/etc/containers/libpod.conf and
    /usr/share/containers/libpod.conf) if not overridden in
    the rootless configuration

  - Added fuse-overlayfs dependency to support overlay based
    rootless image manipulations

  - The podman cp command can now read input redirected to
    STDIN, and output to STDOUT instead of a file, using -
    instead of an argument.

  - The podman remote client now displays version
    information from both the client and server in podman
    version

  - The podman unshare command has been added, allowing easy
    entry into the user namespace set up by rootless Podman
    (allowing the removal of files created by rootless
    podman, among other things)

  - Fixed a bug where Podman containers with the --rm flag
    were removing created volumes when they were
    automatically removed

  - Fixed a bug where container and pod locks were
    incorrectly marked as released after a system reboot,
    causing errors on container and pod removal

    establish remote connections by default

  - Fixed an issue with apparmor_parser (bsc#1123387)

  - Update to libpod v1.4.0 (bsc#1137860) :
