Change Logs

* Fri Jun 04 2021 Christian Goll <cgoll@suse.com>
- Update to version 3.7.4  (boo#1186619)
  Fix for CVE-2021-32635:
  Due to incorrect use of a default URL, singularity action commands
  (run/shell/exec) specifying a container using a library:// URI will always
  attempt to retrieve the container from the default remote endpoint
  (cloud.sylabs.io) rather than the configured remote endpoint. An attacker may
  be able to push a malicious container to the default remote endpoint with a
  URI that is identical to the URI used by a victim with a non-default remote
  endpoint, thus executing the malicious container.
- Disabled ppc64le builds as these are non pie builds and so not
  suiteable for the distribution in SLE and ppc64le is not relevant
  for openSUSE
Version: 2.3.1-2.1
* Thu Oct 05 2017 eich@suse.com
- Removed:
  Do-chdir-before-duing-chroot.patch:
  After checking with the security team that there are no concerns
  about doing the chdir() after the chroot(), remove this patch and
  add a filter to keep rpmlint from complaining (bsc#1028304).
* Mon Oct 02 2017 eich@suse.com
- set permissions for SUID binaries to 4750.
- fix library packaging for i586.
- add a README.SUSE
- temporarily filter filter for non-standard-gid from rpmlint
  until group 'singularity' is available as known group.
* Thu Sep 14 2017 eich@suse.com
- Update to version 2.3.1:
  This release includes a fix for a High Severity security issue on older
  hosts, and other improvements and fixes to previous versions of Singularity.
  Version 2.3:
  There are a massive number of fixes, updates, optimizations and awesomeness
  contained within this release, but here is a brief overview of the major
  changes you can expect to find in this release:
    Lots of backend library changes to accommodate a more flexible API
    Restructured Python backend
    Updated bootstrap backend to make it much more reliable
    Direct support for the awesome, the fantastic, Singularity-Hub!
    Ability to run additional commands without root privileges (e.g. create,
    import, copy, export, etc..).
    Added ability to pull images from Singularity Hub and Docker
    Containers now have labels, and are inspect'able
- Do-chdir-before-duing-chroot.patch:
  Add a chdir() before chroot() just to keep rpmlint from complaining
  even more. There is a chdir("/") right after the chroot() call.
- Created group 'singularity' and make suid-root binaries only executable
  by this group.

Version: 3.6.0-bp152.2.4.1
* Wed Jul 15 2020 Ana Guerrero Lopez <aguerrero@suse.com>
- New version 3.6.0. This version introduces a new signature format
  for SIF images, and changes to the signing / verification code to address
  the following security problems:
  - CVE-2020-13845, bsc#1174150
  In Singularity 3.x versions below 3.6.0, issues allow the ECL to
  be bypassed by a malicious user.
  - CVE-2020-13846, bsc#1174148
  In Singularity 3.5 the --all / -a option to singularity verify
  returns success even when some objects in a SIF container are not signed,
  or cannot be verified.
  - CVE-2020-13847, bsc#1174152
  In Singularity 3.x versions below 3.6.0, Singularity's sign and verify
  commands do not sign metadata found in the global header or data object
  descriptors of a SIF file, allowing an attacker to cause unexpected
  behavior. A signed container may verify successfully, even when it has
  been modified in ways that could be exploited to cause malicious behavior.
- New features / functionalities
  - A new '--legacy-insecure' flag to verify allows verification of SIF
  signatures in the old, insecure format.
  - A new '-l / --logs' flag for instance list that shows the paths
  to instance STDERR / STDOUT log files.
  - The --json output of instance list now include paths to
  STDERR / STDOUT log files.
- Changed defaults / behaviours
  - New signature format (see security fixes above).
  - Fixed spacing of singularity instance list to be dynamically changing
  based off of input lengths instead of fixed number of spaces to account
  for long instance names.
- Deprecate -a / --all option to sign/verify as new signature behavior
  makes this the default.
- For more information about upstream changes, please check:
  https://github.com/hpcng/singularity/blob/master/CHANGELOG.md
* Mon May 25 2020 Ana Guerrero Lopez <aguerrero@suse.com>
- New pre-version 3.6.0 rc5 with many changes:
- New features / functionalities
  - Singularity now supports the execution of minimal Docker/OCI
  containers that do not contain /bin/sh, e.g. docker://hello-world.
  - A new cache structure is used that is concurrency safe on a filesystem that
  supports atomic rename. If you downgrade to Singularity 3.5 or older after
  using 3.6 you will need to run singularity cache clean.
  - A plugin system rework adds new hook points that will allow the
  development of plugins that modify behavior of the runtime. An image driver
  concept is introduced for plugins to support new ways of handling image and
  overlay mounts. Plugins built for <=3.5 are not compatible with 3.6.
  - The --bind flag can now bind directories from a SIF or ext3 image into a
  container.
  - The --fusemount feature to mount filesystems to a container via FUSE
  drivers is now a supported feature (previously an experimental hidden flag).
  - This permits users to mount e.g. sshfs and cvmfs filesystems to the
  container at runtime.
  - A new -c/--config flag allows an alternative singularity.conf to be
  specified by the root user, or all users in an unprivileged installation.
  - A new --env flag allows container environment variables to be set via the
  Singularity command line.
  - A new --env-file flag allows container environment variables to be set from
  a specified file.
  - A new --days flag for cache clean allows removal of items older than a
  specified number of days. Replaces the --name flag which is not generally
  useful as the cache entries are stored by hash, not a friendly name.
- Changed defaults / behaviours
  - Environment variables prefixed with SINGULARITYENV_ always take
  precedence over variables without SINGULARITYENV_ prefix.
  - The %post build section inherits environment variables from the base image.
  - %files from ... will now follow symlinks for sources that are directly
  specified, or directly resolved from a glob pattern. It will not follow
  symlinks found through directory traversal. This mirrors Docker multi-stage
  COPY behaviour.
  - Restored the CWD mount behaviour of v2, implying that CWD path is not recreated
  inside container and any symlinks in the CWD path are not resolved anymore to
  determine the destination path inside container.
  - The %test build section is executed the same manner as singularity test image.
  - -fusemount with the container: default directive will foreground the FUSE
  process. Use container-daemon: for previous behavior.
- Removed --name flag for cache clean; replaced with --days.
- And many bug fixes.
- Update URL, github repository has moved.
- Update patch:
  * build-position-independent-binaries.patch
Version: 3.6.3-bp152.2.8.1
* Fri Sep 18 2020 Ana Guerrero Lopez <aguerrero@suse.com>
- New version 3.6.3, addresses the following security issues:
  - CVE-2020-25039, bsc#1176705
  When a Singularity action command (run, shell, exec) is run with
  the fakeroot or user namespace option, Singularity will extract
  a container image to a temporary sandbox directory.
  Due to insecure permissions on the temporary directory it is possible
  for any user with access to the system to read the contents of the image.
  Additionally, if the image contains a world-writable file or directory,
  it is possible for a user to inject arbitrary content into the running
  container.
  - CVE-2020-25040, bsc#1176707
  When a Singularity command that results in a container
  build operation is executed, it is possible for a user with access
  to the system to read the contents of the image during the build.
  Additionally, if the image contains a world-writable file or directory,
  it is possible for a user to inject arbitrary content into the running
  build, which in certain circumstances may enable arbitrary code execution
  during the build and/or when the built container is run.
* Mon Sep 14 2020 Ana Guerrero Lopez <aguerrero@suse.com>
- New version 3.6.2, new features / functionalities:
  - Add --force option to singularity delete for non-interactive
  workflows.

    overwrite CWD.
  - Don't unset PATH when interpreting legacy /environment files.
- Remove patch, this change is now in upstream:
  * build-position-independent-binaries.patch
Version: 3.6.4-bp152.2.12.1
* Tue Oct 20 2020 Ana Guerrero Lopez <aguerrero@suse.com>
- New version 3.6.4 addresses a security issue:
  - CVE-2020-15229, bsc#1177901
  Due to insecure handling of path traversal and the lack of path
  sanitization within unsquashfs, it is possible to overwrite/create
  files on the host filesystem during the extraction of a crafted
  squashfs filesystem. Affects unprivileged execution of SIF/SquashFS
  images, and image builds from SIF/SquashFS images.

  - A new `Fingerprints:` header in definition files will check that
    a SIF source image can be verified, and is signed with keys
    matching all specified fingerprints.
  - Labels can be set dynamically from a build's `%post` section by
    setting them in the `SINGULARITY_LABELS` environment variable.
  - New `build-arch` label is automatically set to the architecure of
    the host during a container build.
  - New `-D/--description` flag for `singularity push` sets
    description for a library container image.
  - `singularity remote status` shows validity of authentication token if
    set.
  - `singularity push` reports quota usage and URL on successful push
    to a library server that supports this.
  - A new `--no-mount` flag for actions allows a user to disable
    proc/sys/dev/devpts/home/tmp/hostfs/cwd mounts, even if they are
    enabled in `singularity.conf`.
  - Changed defaults / behaviours
  - When actions (run/shell/exec...) are used without `--fakeroot` the
    umask from the calling environment will be propagated into the
    container, so that files are created with expected permissions.
    Use the new `--no-umask` flag to return to the previous behaviour
    of setting a default 0022 umask.
  - Container metadata, environment, scripts are recorded in a
    descriptor in builds to SIF files, and `inspect` will use this if
    present.
  - The `--nv` flag for NVIDIA GPU support will not resolve libraries
    reported by `nvidia-container-cli` via the ld cache. Will instead
    respect absolute paths to libraries reported by the tool, and bind
    all versioned symlinks to them.
  - General re-work of the `remote login` flow, adds prompts and token
    verification before replacing an existing authentication token.
  - The Execution Control List (ECL) now verifies container
    fingerprints using the new global keyring. Previously all users
    would need relevant keys in their own keyring.
  - The SIF layer mediatype for ORAS has been changed to
    `application/vnd.sylabs.sif.layer.v1.sif` reflecting the published
    [opencontainers/artifacts](https://github.com/opencontainers/artifacts/blob/master/artifact-authors.md#defining-layermediatypes)
    value.
  - `SINGULARITY_BIND` has been restored as an environment variable
    set within a running container. It now reflects all user binds
    requested by the `-B/--bind` flag, as well as via
    `SINGULARITY_BIND[PATHS]`.
  - `singularity search` now correctly searches for container images
    matching the host architecture by default. A new `--arch` flag
    allows searching for other architectures. A new results format
    gives more detail about container image results, while users and
    collections are no longer returned.
  - Bug Fixes
  - Support larger definition files, environments etc. by passing
    engine configuration in the environment vs. via socket buffer.
  - Ensure `docker-daemon:` and other source operations respect
    `SINGULARITY_TMPDIR` for all temporary files.
  - Support double quoted filenames in the `%files` section of build
    definitions.
  - Correct `cache list` sizes to show KiB with powers of 1024,
    matching `du` etc.
  - Don't fail on `enable fusemount=no` when no fuse mounts are
    needed.
  - Pull OCI images to the correct requested location when the cache
    is disabled.
  - Ensure `Singularity>` prompt is set when container has no
    environment script, or singularity is called through a wrapper
    script.
  - Avoid build failures in `yum/dnf` operations against the 'setup'
    package on `RHEL/CentOS/Fedora` by ensuring staged `/etc/` files
    do not match distro default content.
  - Failed binds to `/etc/hosts` and `/etc/localtime` in a container
    run with `--contain` are no longer fatal errors.
  - Don't initialize the cache for actions where it is not required.
  - Increase embedded shell interpreter timeout, to allow slow-running
    environment scripts to complete.
  - Correct buffer handling for key import to allow import from STDIN.
  - Reset environment to avoid `LD_LIBRARY_PATH` issues when resolving
    dependencies for the `unsquashfs` sandbox.
  - Fall back to `/sbin/ldconfig` if `ldconfig` on `PATH` fails while
    resolving GPU libraries. Fixes problems on systems using Nix /
    Guix.
  - Address issues caused by error code changes in `unsquashfs`
    version 4.4.
  - Ensure `/dev/kfd` is bound into container for ROCm when `--rocm`
    is used with `--contain`.
  - Tolerate comments on `%files` sections in build definition files.
  - Fix a loop device file descriptor leak.

* Wed May 19 2021 Ferdinand Thiessen <rpm@fthiessen.de>
- Update to version 3.7.3
  Fix for CVE-2021-29136:
  A dependency used to extract docker/OCI image layers can be
  tricked into modifying host files by creating a malicious layer
  that has a symlink with the name "." (or "/"), when running as root.
