libreoffice vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.10
- Ubuntu 16.04 LTS
- 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

Ubuntu 16.04 LTS:
  libreoffice-core                1:5.1.6~rc2-0ubuntu1~xenial2

Ubuntu 14.04 LTS:
  libreoffice-core                1:4.2.8-0ubuntu5.1

After a standard system update you need to restart LibreOffice to make all
the necessary changes.
