Summary
Moby is an open source container framework.
In Docker Engine prior to version 29.5.1, Docker Daemon versions 28.5.2 and prior, and Moby Daemon prior to version 2.0.0-beta.14, a race condition during docker cp mount setup allows a malicious container to redirect a bind mount target to an arbitrary host path, potentially overwriting host files or causing denial of service.
This issue has been patched in Docker Engine version 29.5.1 and Moby Daemon version 2.0.0-beta.14.
- before 29.5.1
- before 2.0.0-beta.14
- through 28.5.2
