libreoffice vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- - Ubuntu 16.10

- - Ubuntu 14.04 LTS
Summary:
LibreOffice could be made to crash or run programs as your login if it
opened a specially crafted EMF file.
Software Description:
- - libreoffice: Office productivity suite
Details:
It was discovered that LibreOffice incorrectly handled EMF image files.
If a user were tricked into opening a specially crafted EMF image file, a
remote attacker could cause LibreOffice to crash, and possibly execute
arbitrary code.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 16.10:
libreoffice-core 1:5.2.2-0ubuntu2.1

the necessary changes.
