CVE-2024-23652

Published: 31 January 2024

BuildKit is a toolkit for converting source code to build artifacts in an efficient, expressive and repeatable manner. 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. The issue has been fixed in v0.12.5. Workarounds include avoiding using BuildKit frontends from an untrusted source or building an untrusted Dockerfile containing RUN --mount feature.

Notes

Traditionally the docker.io source package contained both the
library and docker application. However, in releases that
contain the
docker.io-app source package, the docker.io source package
contains only
the library whilst the docker application itself is contained
in the
docker.io-app package.

docker packages contain an embedded copy of github:moby/buildkit
