Bug description:
  EMBARGOED until 2014-03-10
  PUBLISHED now: http://lists.freedesktop.org/archives/devkit-devel/2014-March/001568.html

  Florian Weimer of the Red Hat Product Security Team found a flaw in
  the way udisks and udisks2 handled long path names. A malicious, local
  user could use this flaw to create a specially-crafted directory
  structure that could lead to arbitrary code execution with the
  privileges of the udisks daemon (root).

  Huzaifa Sidhpurwala created a proposed patch. I don't like the
  changing from PATH_MAX to 4096, but it looks good otherwise.

  I'll handle the upstream bits, Debian and Ubuntu trusty updates and
  discuss the PATH_MAX issue.

  Upstream fix for udisks 2: http://cgit.freedesktop.org/udisks/commit/?id=244967
  Upstream fix for udisks 1: http://cgit.freedesktop.org/udisks/commit/?h=udisks1&id=ebf61ed8471
