Name of the Vulnerable Software and Affected Versions
Docker (affected versions not specified)
Description
When handling 'PUT /containers/{id}/archive' requests with compressed archives, the daemon decompresses them using external system binaries. Due to incorrect operation ordering, these binaries are resolved from the container filesystem instead of the host filesystem. A container image containing a trojanized decompression binary can achieve arbitrary code execution with daemon privileges, including host root UID and unrestricted capabilities, crossing the container-to-host trust boundary. This occurs when a user runs a container from a malicious image and uploads a compressed archive (xz or gzip) via the 'PUT /containers/{id}/archive' API or by piping a compressed archive through
docker cp -.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
Only run containers from trusted images.
Use authorization plugins to limit access to the 'PUT /containers/{id}/archive' endpoint.
Avoid piping compressed archives into containers created from untrusted images.
