From $URL :

Timo Warns (Warns@Pre-Sense.DE) reported publicly that OpenOffice and
LibreOffice (as well as other Office Suites) fail to appropriately warn users
when a file with embedded content is opened. Additionally it is not possible
to disable the opening of embedded content within files. This can be used to
add tracking behavior to files or to deliver additional files that can
potentially exploit other security issues when parsed to the user.
Additionally if the file is converted (e.g. to a PDF) and then saved the
converted file may contain a direct copy of the embedded data, thus if
something sensitive if referenced (such as ~/.ssh/id_rsa) this information may
then be exposed if the resulting file is shared.

@maintainer, please check if this suite is affected

The discussion for this bug is http://seclists.org/oss-sec/2012/q4/453 where CVE-2012-5639 was assigned. 

Although the initial bug report also mention {open,libre}office, this is being tracked in bug 447380. LibreOffice states this is fixed in 4.2 by introducing a stealth mode: http://whatofhow.wordpress.com/2013/12/02/stealth-mode/ (from https://bugs.freedesktop.org/show_bug.cgi?id=58295#c2 ) 

Input from goffice maintainers would be appreciated.
