Aleksandar Nikolic discovered that missing input sanitising in
the RTF parser in Libreoffice may result in the execution of
arbitrary code if a malformed documented is opened.
For Debian 7 Wheezy, these problems have been fixed in version
1:3.5.4+dfsg2-0+deb7u7.
We recommend that you upgrade your libreoffice packages.
