This update for singularity fixes the following issues:

New version 3.6.3, addresses the following security issues:

- CVE-2020-25039, boo#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, boo#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.

New version 3.6.2, new features / functionalities:

  -Add --force option to singularity delete for non-interactive 
   workflows.
  -Support compilation with FORTIFY_SOURCE=2 and build in pie mode 
   with fstack-protector enabled
  - Changed defaults / behaviours
   -Default to current architecture for singularity delete.
  - Bug Fixes
   -Respect current remote for singularity delete command.
   -Allow rw as a (noop) bind option.
   -Fix capability handling regression in overlay mount.
   -Fix LD_LIBRARY_PATH environment override regression with --nv/--rocm.
   -Fix environment variable duplication within singularity engine.
   -Use -user-xattrs for unsquashfs to avoid error with rootless 
    extraction using unsquashfs 3.4
   -Correct --no-home message for 3.6 CWD behavior.
   -Don't fail if parent of cache dir not accessible.
   -Fix tests for Go 1.15 Ctty handling.
   -Fix additional issues with test images on ARM64.
   -Fix FUSE e2e tests to use container ssh_config.
   -Provide advisory message r.e. need for upper and work to exist 
    in overlay images.
   -Use squashfs mem and processor limits in squashfs gzip check.
   -Ensure build destination path is not an empty string - do not 
    overwrite CWD.
   -Don't unset PATH when interpreting legacy /environment files.
