CVE-2024-23653

Published: 31 January 2024

BuildKit is a toolkit for converting source code to build artifacts in an efficient, expressive and repeatable manner. 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. The issue has been fixed in v0.12.5 . Avoid using BuildKit frontends from untrusted sources.

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
