    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
    in version 1:3.5.4+dfsg2-0+deb7u5.
    
    For the stable distribution (jessie), these problems have been fixed in
    version 1:4.3.3-2+deb8u2.
    
    For the testing distribution (stretch), these problems have been fixed
    in version 1:5.0.2-1.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 1:5.0.2-1.
    
    We recommend that you upgrade your libreoffice packages.
