Bug description:
  The developers of the Shibboleth SP have released a security advisory
  that affects all current versions of shibboleth-sp prior to V2.6.1.
  This includes the versions currently available for all releases of
  Ubuntu.

  The full text of the advisory is available at
  https://shibboleth.net/community/advisories/secadv_20171115.txt

  The vulnerability allows a remote attacker to bypass security checks
  on dynamically loaded metadata, a scenario that's commonly used in
  federated environments, and thus a likely use-case for this package.
  It is likely that a significant proportion of users of this package
  will be affected.

  From the advisory: "There are no known mitigations to prevent this
  attack apart from applying this update. Deployers should take
  immediate steps, and may wish to disable the use of this feature until
  the upgrade is done."
