Ubuntu Security Notice USN-1536-1
August 13, 2012

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

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

- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04

Summary:

LibreOffice could be made to crash or run programs as your login if it
opened a specially crafted file.

Software Description:
- libreoffice: Office productivity suite

Details:

It was discovered that LibreOffice incorrectly handled certain encryption
tags in Open Document Text (.odt) files. If a user were tricked into
opening a specially crafted file, an attacker could cause LibreOffice to
crash or possibly execute arbitrary code with the privileges of the user
invoking the program.

Update instructions:

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

Ubuntu 12.04 LTS:
  libreoffice-core                1:3.5.4-0ubuntu1.1

Ubuntu 11.10:
  libreoffice-core                1:3.4.4-0ubuntu1.4

Ubuntu 11.04:
  libreoffice-core                1:3.3.4-0ubuntu1.4

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