   An update that fixes one vulnerability is now available.

Description:



   Singularity was updated to version 2.6.0, bringing features, bugfixes and
   security fixes.

   Security issues fixed:

   - CVE-2018-12021: Fixed access control on systems supporting overlay file
     system (boo#1100333).

   Highlights of 2.6.0:

   - Allow admin to specify a non-standard location for mksquashfs binary at
     build time with '--with-mksquashfs' option #1662
   - '--nv' option will use
     [nvidia-container-cli](https://github.com/NVIDIA/libnvidia-container) if
     installed #1681
   - [nvliblist.conf]
   (https://github.com/singularityware/singularity/blob/master/etc/nvliblist.c
     onf) now has a section for binaries #1681
   - '--nv' can be made default with all action commands in
 singularity.conf
     #1681
   - '--nv' can be controlled by env vars '$SINGULARITY_NV' and
     '$SINGULARITY_NV_OFF' #1681
   - Restore shim init process for proper signal handling and child reaping
     when container is initiated in its own PID namespace #1221
   - Add '-i' option to image.create to specify the inode ratio. #1759
   - Bind '/dev/nvidia*' into the container when the '--nv'
 flag is used in
     conjuction with the '--contain' flag #1358
   - Add '--no-home' option to not mount user $HOME if it is not the
 $CWD and
     'mount home = yes' is set. #1761
   - Added support for OAUTH2 Docker registries like Azure Container Registry
     #1622

   Highlights of 2.5.2:

   - a new `build` command was added to replace `create` + `bootstrap`
   - default image format is squashfs, eliminating the need to specify a size
   - a `localimage` can be used as a build base, including ext3, sandbox, and
     other squashfs images
   - singularity hub can now be used as a base with the uri
   - Restore docker-extract aufs whiteout handling that implements correct
     extraction of docker container layers.

   Bug fixes:

   - Fix 404 when using Arch Linux bootstrap #1731
   - Fix environment variables clearing while starting instances #1766
   - several more bug fixes, see CHANGELOG.md for details
