Package : libreoffice
CVE ID : CVE-2015-4551 CVE-2015-5212 CVE-2015-5213 CVE-2015-5214

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
https://www.libreoffice.org/about-us/security/advisories/cve-2015-4551/:
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 oect memory management in parsing
Microsoft Word documents may result in the execution of arbitrary code.

For the oldstable distribution (wheezy), these problems have been fixed
