"The version of LibreOffice installed on the remote Mac OS X host is
prior to 4.2.8 or 4.3.x prior to 4.3.5. It is, therefore, affected by
an invalid memory write vulnerability. An attacker, using a specially
crafted Rich Text Format (RTF) file, can exploit this to cause a
denial of service or possibly execute arbitrary code.

Note that Nessus has not attempted to exploit this issue but has
instead relied only on the application's self-reported version number.");
