| VCID-3eju-5upk-auhy | `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 security@docker.com if you think you’ve found a security bug |

| VCID-bhju-575k-ebh3 | Docker CLI leaks private registry credentials to registry-1.docker.io ## Impact A bug was found in the Docker CLI where running `docker login my-private-registry.example.com` with a misconfigured configuration file (typically `~/.docker/config.json`) listing a `credsStore` or `credHelpers` that could not be executed would result in any provided credentials being sent to `registry-1.docker.io` rather than the intended private registry. ## Patches This bug has been fixed in Docker CLI 20.10.9. Users should update to this version as soon as possible. ## Workarounds Ensure that any configured `credsStore` or `credHelpers` entries in the configuration file reference an installed credential helper that is executable and on the `PATH`. ## For more information If you have any questions or comments about this advisory: * [Open an issue](https://github.com/docker/cli/issues/new/choose) * Email us at security@docker.com if you think you’ve found a security bug |
CVE-2021-41092
GHSA-99pg-grm5-qq3v |
| VCID-e9ng-x516-53cf | 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 like to thank Joan Bruguera 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 security@docker.com if you think you’ve found a security bug |
