GHSA-v994-f8vw-g7j4: `docker cp` allows unexpected chmod of host files in Moby Docker Engine

## Impact A bug was found in Moby (Docker Engine) where attempting to copy files using `docker cp` into a specially-crafted container can result in Unix file permission changes for existing files in the host’s filesystem, widening access to others. This bug does not directly allow files to be read, modified, or executed without an additional cooperating process. ## Patches This bug has been fixed in Moby (Docker Engine) 20.10.9. Users should update to this version as soon as possible. Running containers do not need to be restarted. ## Workarounds Ensure you only run trusted containers. ## Credits The Moby project would like to thank Lei Wang and Ruizhi Xiao for responsibly disclosing this issue in accordance with the [Moby security policy](https://github.com/moby/moby/blob/master/SECURITY.md). ## For more information If you have any questions or comments about this advisory: * [Open an issue](https://github.com/moby/moby/issues/new) * Email us at  [email protected]  if you th...

GHSA-xw73-rw38-6vjc: Moby vulnerable to classic builder cache poisoning

The classic builder cache system is prone to cache poisoning if the image is built `FROM scratch`. Also, changes to some instructions (most important being `HEALTHCHECK` and `ONBUILD`) would not cause a cache miss. An attacker with the knowledge of the Dockerfile someone is using could poison their cache by making them pull a specially crafted image that would be considered as a valid cache candidate for some build steps. For example, an attacker could create an image that is considered as a valid cache candidate for: ``` FROM scratch MAINTAINER Pawel ``` when in fact the malicious image used as a cache would be an image built from a different Dockerfile. In the second case, the attacker could for example substitute a different `HEALTCHECK` command. ### Impact 23.0+ users are only affected if they explicitly opted out of Buildkit (`DOCKER_BUILDKIT=0` environment variable) or are using the `/build` API endpoint (which uses the classic builder by default). All users on versions ...

GHSA-3fwx-pjgw-3558: Moby (Docker Engine) Insufficiently restricted permissions on data directory

## Impact A bug was found in Moby (Docker Engine) where the data directory (typically `/var/lib/docker`) contained subdirectories with insufficiently restricted permissions, allowing otherwise unprivileged Linux users to traverse directory contents and execute programs. When containers included executable programs with extended permission bits (such as `setuid`), unprivileged Linux users could discover and execute those programs. When the UID of an unprivileged Linux user on the host collided with the file owner or group inside a container, the unprivileged Linux user on the host could discover, read, and modify those files. ## Patches This bug has been fixed in Moby (Docker Engine) 20.10.9. Users should update to this version as soon as possible. Running containers should be stopped and restarted for the permissions to be fixed. ## Workarounds Limit access to the host to trusted users. Limit access to host volumes to trusted containers. ## Credits The Moby project would li...

GHSA-9p26-698r-w4hx: BuildKit vulnerable to possible panic when incorrect parameters sent from frontend

### Impact A malicious BuildKit client or frontend could craft a request that could lead to BuildKit daemon crashing with a panic. ### Patches The issue has been fixed in v0.12.5 ### Workarounds Avoid using BuildKit frontends from untrusted sources. A frontend image is usually specified as the `#syntax` line on your Dockerfile, or with `--frontend` flag when using `buildctl build` command. ### References

GHSA-m3r6-h7wv-7xxv: BuildKit vulnerable to possible race condition with accessing subpaths from cache mounts

### Impact Two malicious build steps running in parallel sharing the same cache mounts with subpaths could cause a race condition that can lead to files from the host system being accessible to the build container. ### Patches The issue has been fixed in v0.12.5 ### Workarounds Avoid using BuildKit frontend from an untrusted source or building an untrusted Dockerfile containing cache mounts with `--mount=type=cache,source=...` options. ### References https://www.openwall.com/lists/oss-security/2019/05/28/1

GHSA-4v98-7qmw-rqr8: BuildKit vulnerable to possible host system access from mount stub cleaner

### Impact A malicious BuildKit frontend or Dockerfile using `RUN --mount` could trick the feature that removes empty files created for the mountpoints into removing a file outside the container, from the host system. ### Patches The issue has been fixed in v0.12.5 ### Workarounds Avoid using BuildKit frontend from an untrusted source or building an untrusted Dockerfile containing `RUN --mount` feature. ### References

GHSA-wr6v-9f75-vh2g: Buildkit's interactive containers API does not validate entitlements check

### Impact In addition to running containers as build steps, BuildKit also provides APIs for running interactive containers based on built images. It was possible to use these APIs to ask BuildKit to run a container with elevated privileges. Normally, running such containers is only allowed if special `security.insecure` entitlement is enabled both by buildkitd configuration and allowed by the user initializing the build request. ### Patches The issue has been fixed in v0.12.5 . ### Workarounds Avoid using BuildKit frontends from untrusted sources. A frontend image is usually specified as the `#syntax` line on your Dockerfile, or with `--frontend` flag when using `buildctl build` command. ### References

GHSA-gc89-7gcr-jxqc: Buildkit credentials inlined to Git URLs could end up in provenance attestation

When the user sends a build request that contains a Git URL that contains credentials and the build creates a provenance attestation describing that build, these credentials could be visible from the provenance attestation. Git URL can be passed in two ways: 1) Invoking build directly from a URL with credentials. ``` buildctl build --frontend dockerfile.v0 --context https://<credentials>@url/repo.git ``` Equivalent in `docker buildx` would be ``` docker buildx build https://<credentials>@url/repo.git ``` 2) If the client sends additional VCS info hint parameters on builds from a local source. Usually, that would mean reading the origin URL from `.git/config` file. Thanks to Oscar Alberto Tovar for discovering the issue. ### Impact When a build is performed under specific conditions where credentials were passed to BuildKit they may be visible to everyone who has access to provenance attestation. Provenance attestations and VCS info hints were added in version v0.11.0. Previou...

CVE-2023-26054: Merge pull request from GHSA-gc89-7gcr-jxqc · moby/buildkit@75123c6

BuildKit is a toolkit for converting source code to build artifacts in an efficient, expressive and repeatable manner. In affected versions when the user sends a build request that contains a Git URL that contains credentials and the build creates a provenance attestation describing that build, these credentials could be visible from the provenance attestation. Git URL can be passed in two ways: 1) Invoking build directly from a URL with credentials. 2) If the client sends additional version control system (VCS) info hint parameters on builds from a local source. Usually, that would mean reading the origin URL from `.git/config` file. When a build is performed under specific conditions where credentials were passed to BuildKit they may be visible to everyone who has access to provenance attestation. Provenance attestations and VCS info hints were added in version v0.11.0. Previous versions are not vulnerable. In v0.10, when building directly from Git URL, the same URL could be visible ...

GHSA-rc4r-wh2q-q6c4: Moby supplementary group permissions not set up properly, allowing attackers to bypass primary group restrictions

Moby is an open-source project created by Docker to enable software containerization. A bug was found in Moby (Docker Engine) where supplementary groups are not set up properly. If an attacker has direct access to a container and manipulates their supplementary group access, they may be able to use supplementary group access to bypass primary group restrictions in some cases, potentially gaining access to sensitive information or gaining the ability to execute code in that container. This bug is fixed in Moby (Docker Engine) 20.10.18. Users should update to this version when it is available. Running containers should be stopped and restarted for the permissions to be fixed. For users unable to upgrade, this problem can be worked around by not using the `"USER $USERNAME"` Dockerfile instruction. Instead by calling `ENTRYPOINT ["su", "-", "user"]` the supplementary groups will be set up properly. Thanks to Steven Murdoch for reporting this issue. ---- ### Impact If an attacker has d...

CVE-2022-2990: Vulnerability in Linux containers – investigation and mitigation

An incorrect handling of the supplementary groups in the Buildah container engine might lead to the sensitive information disclosure or possible data modification if an attacker has direct access to the affected container where supplementary groups are used to set access permissions and is able to execute a binary code in that container.

CVE-2022-29085: DSA-2022-021: Dell Unity, Dell UnityVSA, and Dell Unity XT Security Update for Multiple Vulnerabilities

Dell Unity, Dell UnityVSA, and Dell Unity XT versions prior to 5.2.0.0.5.173 contain a plain-text password storage vulnerability when certain off-array tools are run on the system. The credentials of a user with high privileges are stored in plain text. A local malicious user with high privileges may use the exposed password to gain access with the privileges of the compromised user.

CVE-2021-41091: Merge pull request #2 from moby/20.10-GHSA-3fwx-pjgw-3558_0701-perms · moby/moby@f0ab919

Moby is an open-source project created by Docker to enable software containerization. A bug was found in Moby (Docker Engine) where the data directory (typically `/var/lib/docker`) contained subdirectories with insufficiently restricted permissions, allowing otherwise unprivileged Linux users to traverse directory contents and execute programs. When containers included executable programs with extended permission bits (such as `setuid`), unprivileged Linux users could discover and execute those programs. When the UID of an unprivileged Linux user on the host collided with the file owner or group inside a container, the unprivileged Linux user on the host could discover, read, and modify those files. This bug has been fixed in Moby (Docker Engine) 20.10.9. Users should update to this version as soon as possible. Running containers should be stopped and restarted for the permissions to be fixed. For users unable to upgrade limit access to the host to trusted users. Limit access to host v...

Moby is an open-source project created by Docker to enable software containerization. A bug was found in Moby (Docker Engine) where attempting to copy files using `docker cp` into a specially-crafted container can result in Unix file permission changes for existing files in the host’s filesystem, widening access to others. This bug does not directly allow files to be read, modified, or executed without an additional cooperating process. This bug has been fixed in Moby (Docker Engine) 20.10.9. Users should update to this version as soon as possible. Running containers do not need to be restarted.
