libreoffice - security update

Multiple vulnerabilities have been discovered in LibreOffice, a
full-featured office productivity:

• CVE-2015-4551
  Federico Scrinzi discovered an information leak in the handling of
  ODF documents. Quoting from
  :
  The LinkUpdateMode feature controls whether documents inserted into
  Writer or Calc via links will either not get updated, or prompt to
  update, or automatically update, when the parent document is loaded.
  The configuration of this option was stored in the document. That
  flawed approach enabled documents to be crafted with links to
  plausible targets on the victims host computer. The contents of
  those automatically inserted after load links can be concealed in
  hidden sections and retrieved by the attacker if the document is
  saved and returned to sender, or via http requests if the user has
  selected lower security settings for that document.
• CVE-2015-5212
  A buffer overflow in parsing the printer setup information in ODF
  documents may result in the execution of arbitrary code.
• CVE-2015-5213 /
  CVE-2015-5214
  A buffer overflow and an integer overflow in parsing
  Microsoft Word documents may result in the execution of arbitrary code.
