Security Related Fixes

Changed Defaults / Behaviours

Although SingularityCE does not aim to contain execution / prevent host modification when started as the host root user, the following changes have been adopted to permit finer control over the use of external binaries, with a modified default search path when singularity is run as the host root user:

  • When started as host root, external binaries (except those with explicit configuration entries) are now found using the root search path in singularity.conf. By default this excludes searching the environment $PATH. Add $PATH: to the start of root search path in singularity.conf to restore previous behavior.
  • When started as non-root / fake root, external binaries (except those with explicit configuration entires) are now found using the user search path in singularity.conf. By default this includes $PATH, so there is no effective behaviour change vs previous versions.

Thank you to @KoseceMehmet for suggesting this change.

SingularityCE 4.4.1

Bug Fixes

  • Use lazy unmount for overlay items that are FUSE mounted, to prevent errors if unmount takes time due to the device being busy. We already use lazy (MNT_DETACH) for kernel mounted overlay items.
  • Address FUSE unmount error that can occur with short-lived containers on busy systems.
  • Fix spurious cleanup error message when cleanup is successful.

Requirements / Packaging

  • Requires Go 1.25.7 or above, due to various dependencies.

SingularityCE 4.4.0

This is a new minor version, focused around modernisation of code and bugfix improvements as detailed below.

Bug Fixes

  • Include the home directory in the --workdir option (which is a modifier of the --contain option). This has always been in the
    --workdir usage description but the home directory has not actually been included at least since singularity-2.
  • Avoid a fatal error when starting fakeroot from suid mode while in an NFS directory.
  • Support hosts that have /etc/resolv.conf pointing to a symlink under /run, such as those hosts that are running systemd-resolved. In this case, the symlink is copied into the container and the parent directory of the target of the symlink is bind-mounted from the host. The result is that even if the target of the symlink is replaced with a new file, the container sees the update in /etc/resolv.conf.
  • Correctly escape ENV vars when importing OCI containers to native SIF, so that they match podman / docker behaviour.
  • Clarify error when trying to build --oci from a non-Dockerfile spec.
  • When images are pulled implicitly by actions (run/shell/exec...), and the cache is disabled, correctly clean up the temporary files.
  • Ensure singularity-buildkitd runs effective GC at the start of each run.
  • Apply --debug flag to buildkit logging correctly.
  • Avoid OOM by buffering docker-daemon: images via a temporary file instead of memory. Note that the file is created in $TMPDIR - the dependency involved cannot be instructed to use $SINGULARITY_TMPDIR at this time.

New Features & Functionality

  • Add /etc/resolv.conf to the list of host paths that can be prevented from automatic import into the container with the --no-mount option.

Requirements / Packaging

  • Requires Go 1.25.6 or above, due to various dependencies.
