libreoffice vulnerability
============================================================================

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

- Ubuntu 14.10
- Ubuntu 14.04 LTS

Summary:

LibreOffice could be made to crash or run programs if it received specially
crafted network traffic.

Software Description:
- libreoffice: Office productivity suite

Details:

It was discovered that LibreOffice incorrectly handled the Impress remote
control port. An attacker could possibly use this issue to cause Impress to
crash, resulting in a denial of service, or possibly execute arbitrary
code.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 14.10:
  libreoffice-core                1:4.3.3-0ubuntu1

This update uses a new upstream release, which includes additional bug
fixes. After a standard system update you need to restart LibreOffice to
make all the necessary changes.
