  <summary>Security update for apptainer</summary>
  <description>This update for apptainer fixes the following issues:

- Make sure, digest values handled by the Go library
  github.com/opencontainers/go-digest and used throughout the
  Go-implemented containers ecosystem are always validated. This
  prevents attackers from triggering unexpected authenticated
  registry accesses. (CVE-2024-3727, boo#1224114).

- Updated apptainer to version 1.3.0
  * FUSE mounts are now supported in setuid mode, enabling full
    functionality even when kernel filesystem mounts are insecure due to
    unprivileged users having write access to raw filesystems in
    containers. When allow `setuid-mount extfs = no` (the default) in
    apptainer.conf, then the fuse2fs image driver will be used to mount
    ext3 images in setuid mode instead of the kernel driver (ext3 images
    are primarily used for the `--overlay` feature), restoring
    functionality that was removed by default in Apptainer 1.1.8 because
    of the security risk.
    The allow `setuid-mount squashfs` configuration option in
    `apptainer.conf` now has a new default called `iflimited` which allows
    kernel squashfs mounts only if there is at least one `limit container`
    option set or if Execution Control Lists are activated in ecl.toml.
    If kernel squashfs mounts are are not allowed, then the squashfuse
    image driver will be used instead.
    `iflimited` is the default because if one of those limits are used
    the system administrator ensures that unprivileged users do not have
    write access to the containers, but on the other hand using FUSE
    would enable a user to theoretically bypass the limits via `ptrace()`
    because the FUSE process runs as that user.
    The `fuse-overlayfs` image driver will also now be tried in setuid
    mode if the kernel overlayfs driver does not work (for example if
    one of the layers is a FUSE filesystem).  In addition, if `allow
    setuid-mount encrypted = no` then the unprivileged gocryptfs format
    will be used for encrypting SIF files instead of the kernel
    device-mapper. If a SIF file was encrypted using the gocryptfs
    format, it can now be mounted in setuid mode in addition to
    non-setuid mode.
  * Change the default in user namespace mode to use either kernel
    overlayfs or fuse-overlayfs instead of the underlay feature for the
    purpose of adding bind mount points. That was already the default in
    setuid mode; this change makes it consistent. The underlay feature
    can still be used with the `--underlay` option, but it is deprecated
    because the implementation is complicated and measurements have
    shown that the performance of underlay is similar to overlayfs and
    fuse-overlayfs.
    For now the underlay feature can be made the default again with a
    new `preferred` value on the `enable underlay` configuration option.
    Also the `--underlay` option can be used in setuid mode or as the
    root user, although it was ignored previously.
  * Prefer again to use kernel overlayfs over fuse-overlayfs when a
    lower layer is FUSE and there's no writable upper layer, undoing the
    change from 1.2.0. Another workaround was found for the problem that
    change addressed. This applies in both setuid mode and in user
    namespace mode.
  * `--cwd` is now the preferred form of the flag for setting the
    container's working directory, though `--pwd` is still supported for
    compatibility.
  * The way `--home` is handled when running as root (e.g. sudo apptainer)
    or with `--fakeroot` has changed. Previously, we were only modifying
    the `HOME` environment variable in these cases, while leaving the
    container's `/etc/passwd` file unchanged (with its homedir field
    pointing to `/root`, regardless of the value passed to `--home`). With
    this change, both value of HOME and the contents of `/etc/passwd` in
    the container will reflect the value passed to `--home` if the
    container is readonly. If the container is writable, the
    `/etc/passwd` file is left alone because it can interfere with
    commands that want to modify it.
  * The `--vm` and related flags to start apptainer inside a VM have been
    removed. This functionality was related to the retired Singularity Desktop
    / SyOS projects.
  * The keyserver-related commands that were under `remote` have been moved to
    their own, dedicated `keyserver` command. Run `apptainer help keyserver`
    for more information.
  * The commands related to OCI/Docker registries that were under `remote` have
    been moved to their own, dedicated `registry` command. Run
    `apptainer help registry` for more information.
  * The the `remote list` subcommand now outputs only remote endpoints (with
    keyservers and OCI/Docker registries having been moved to separate
    commands), and the output has been streamlined.
  * Adding a new remote endpoint using the `apptainer remote add` command will
    now set the new endpoint as default. This behavior can be suppressed by
    supplying the `--no-default` (or `-n`) flag to `remote add`.
  * Skip parsing build definition file template variables after comments
    beginning with a hash symbol.
  * The global `/tmp` directory is no longer used for gocryptfs mountpoints.
- New Features &amp; Functionality
  * The `remote status` command will now print the username, realname, and
    email of the logged-in user, if available.
  * Add monitoring feature support, which requires the usage of an
    additional tool named `apptheus`, this tool will put apptainer starter
    into a newly created cgroup and collect system metrics.
  * A new `--no-pid` flag for `apptainer run/shell/exec` disables the PID
    namespace inferred by `--containall` and `--compat`.
  * Added `--config` option to `keyserver` commands.
  * Honor an optional remoteName argument to the `keyserver list` command.
  * Added the `APPTAINER_ENCRYPTION_PEM_DATA` env var to allow for
    encrypting and running encrypted containers without a PEM file.
  * Adding `--sharens` mode for `apptainer exec/run/shell`, which enables to
    run multiple apptainer instances created by the same parent using
    the same image in the same user namespace.
- Make 'gocryptfs' an optional dependency.
- Make apptainer definition templates version dependent.

- Fix 'apptainer build' using signed packages from the SUSE
  Registry (boo#1221364).

- Updated apptainer to version 1.2.5
  * Added `libnvidia-nvvm` to `nvliblist.conf`. Newer NVIDIA
    Drivers (known with &gt;= 525.85.05) require this lib to compile
    OpenCL programs against NVIDIA GPUs, i.e. `libnvidia-opencl`
    depends on `libnvidia-nvvm`.
  * Disable the usage of cgroup in instance creation when
    `--fakeroot` is passed.
  * Disable the usage of cgroup in instance creation when `hidepid`
    mount option on `/proc` is set.
  * Fixed a regression introduced in 1.2.0 where the user's
    password file information was not copied in to the container
    when there was a parent root-mapped user namespace (as is the
    case for example in `cvmfsexec`).
  * Added the upcoming NVIDIA driver library `libnvidia-gpucomp.so`
    to the list of libraries to add to NVIDIA GPU-enabled
    containers. Fixed missing error handling during the creation
    of an encrypted image that lead to the generation of corrupted
    images.
  * Use `APPTAINER_TMPDIR` for temporary files during privileged
    image encryption.
  * If rootless unified cgroups v2 is available when starting an
    image but `XDG_RUNTIME_DIR` or `DBUS_SESSION_BUS_ADDRESS` is
    not set, print an info message that stats will not be available
    instead of exiting with a fatal error.
  * Allow templated build arguments to definition files to have
    empty values.
- Package .def templates separately for different SPs.

- Do not build squashfuse, require it as a dependency.
- Replace awkward 'Obsoletes: singularity-*' as well as the
  'Provides: Singularity' by 'Conflicts:' and drop the provides -
  the versioning scheme does not match and we do not automatically
  migrate from one to the other.
- Exclude platforms which do not provide all build dependencies.

- updated to 1.2.3 with following changes:
  * The apptainer push/pull commands now show a progress bar for the oras
    protocol like there was for docker and library protocols.
  * The --nv and --rocm flags can now be used simultaneously.
  * Fix the use of APPTAINER_CONFIGDIR with apptainer instance start and action
    commands that refer to instance://.
  * Fix the issue that apptainer would not read credentials from the Docker
    fallback path ~/.docker/config.json if missing in the apptainer
    credentials.

- updated to 1.2.2 with following changes:
  * Fix $APPTAINER_MESSAGELEVEL to correctly set the logging level.
  * Fix build failures when in setuid mode and unprivileged user namespaces are
    unavailable and the --fakeroot option is not selected.

- updated to 1.2.1 to fix CVE-2023-38496 although not relevant as package is 
  compiled with setuid

- update to 1.2.0 with following changes:
  * binary is built reproducible which disables plugins
  * Create the current working directory in a container when it doesn't exist.
    This restores behavior as it was before singularity 3.6.0. As a result,
    using --no-mount home won't have any effect when running apptainer from a
    home directory and will require --no-mount home,cwd to avoid mounting that
    directory.
  * Handle current working directory paths containing symlinks both on the host
    and in a container but pointing to different destinations. If detected, the
    current working directory is not mounted when the destination directory in
    the container exists.
  * Destination mount points are now sorted by shortest path first to ensure
    that a user bind doesn't override a previous bind path when set in
    arbitrary order on the CLI. This is also applied to image binds.
  * When the kernel supports unprivileged overlay mounts in a user namespace,
    the container will be constructed by default using an overlay instead of an
    underlay layout for bind mounts. A new --underlay action option can be used
    to prefer underlay instead of overlay.
  * sessiondir maxsize in apptainer.conf now defaults to 64 MiB for new
    installations. This is an increase from 16 MiB in prior versions.
  * The apptainer cache is now architecture aware, so the same home directory
    cache can be shared by machines with different architectures.
  * Overlay is blocked on the panfs filesystem, allowing sandbox directories to
    be run from panfs without error.
  * Lookup and store user/group information in stage one prior to entering any
    namespaces, to fix an issue with winbind not correctly looking up
    user/group information when using user namespaces.
- New features / functionalities
  * Support for unprivileged encryption of SIF files using gocryptfs.  This is
    not compatible with privileged encryption, so containers encrypted by root
    need to be rebuilt by an unprivileged user.
  * Templating support for definition files. Users can now define variables in
    definition files via a matching pair of double curly brackets. Variables of
    the form {{ variable }} will be replaced by a value defined either by a
    variable=value entry in the %arguments section of the definition file or
    through new build options --build-arg or --build-arg-file.
  * Add a new instance run command that will execute the runscript when an
    instance is initiated instead of executing the startscript.
  * The sign and verify commands now support signing and verification with
    non-PGP key material by specifying the path to a private key via the --key
    flag.
  * The verify command now supports verification with X.509 certificates by
    specifying the path to a certificate via the --certificate flag. By
    default, the system root certificate pool is used as trust anchors unless
    overridden via the --certificate-roots flag. A pool of intermediate
    certificates that are not trust anchors, but can be used to form a
    certificate chain, can also be specified via the
    --certificate-intermediates flag.
  * Support for online verification checks of X.509 certificates using OCSP
    protocol via the new verify --ocsp-verify option.
  * The instance stats command displays the resource usage every second. The
    --no-stream option disables this interactive mode and shows the
    point-in-time usage.
  * Instances are now started in a cgroup by default, when run as root or when
    unified cgroups v2 with systemd as manager is configured. This allows
    apptainer instance stats to be supported by default when possible.
  * The instance start command now accepts an optional --app &lt;name&gt; argument
    which invokes a start script within the %appstart &lt;name&gt; section in the
    definition file. The instance stop command still only requires the instance
    name.
  * The instance name is now available inside an instance via the new
    APPTAINER_INSTANCE environment variable.
  * The --no-mount flag now accepts the value bind-paths to disable mounting of
    all bind path entries in apptainer.conf.
    Support for DOCKER_HOST parsing when using docker-daemon://
    DOCKER_USERNAME and DOCKER_PASSWORD supported without APPTAINER_ prefix.
    Add new Linux capabilities CAP_PERFMON, CAP_BPF, and CAP_CHECKPOINT_RESTORE.
  * The remote get-login-password command allows users to retrieve a remote's
    token. This enables piping the secret directly into docker login while
    preventing it from showing up in a shell's history.
  * Define EUID in %environment alongside UID.
  * In --rocm mode, the whole of /dev/dri is now bound into the container when
    --contain is in use. This makes /dev/dri/render devices available, required
    for later ROCm versions.

- update to 1.1.9 with following changes:
  * Remove warning about unknown xino=on option from fuse-overlayfs, introduced
    in 1.1.8.
  * Ignore extraneous warning from fuse-overlayfs about a readonly /proc.
  * Fix dropped "n" characters on some platforms in definition file stored as
    part of SIF metadata.
  * Remove duplicated group ids.
  * Fix not being able to handle multiple entries in LD_PRELOAD when binding
    fakeroot into container during apptainer startup for --fakeroot with
    fakeroot command.

- Included a fix for CVE-2023-30549 which is a vulnerability in setuid-root
  installations of Apptainer iwhich was not active in the recent openSUSE
  packages. Still this is included for completenss. The fix adds allow
  setuid-mount configuration options encrypted, squashfs, and extfs, and makes
  the default for extfs be "no". That disables the use of extfs mounts
  including for overlays or binds while in the setuid-root mode, while leaving
  it enabled for unprivileged user namespace mode. The default for encrypted
  and squashfs is "yes".
- Other bug fixes:
  * Fix loop device 'no such device or address' spurious errors when using shared
    loop devices.
  * Add xino=on mount option for writable kernel overlay mount points to fix
    inode numbers consistency after kernel cache flush (not applicable to
    fuse-overlayfs).

- updated to 1.1.7 with following changes:
  * Allow gpu options such as --nv to be nested by always inheriting all
    libraries bound in to a parent container's /.singularity.d/libs.
  * Map the user's home directory to the root home directory by default in the
    non-subuid fakeroot mode like it was in the subuid fakeroot mode, for both
    action commands and building containers from definition files.
  * Make the error message more helpful in another place where a remote is
    found to have no library client.
  * Avoid incorrect error when requesting fakeroot network.
  * Pass computed LD_LIBRARY_PATH to wrapped unsquashfs. Fixes issues where
    unsquashfs on host uses libraries in non-default paths.
