"The version of LibreOffice installed on the remote Windows host is
prior to 4.4.6 or 5.x prior to 5.0.1. It is, therefore, affected by a
memory corruption issue in 'filter/ww8/ww8scan.cxx' due to improper
validation of user-supplied input when handling bookmark status
positions. A remote attacker can exploit this, via a specially crafted
document, to cause a denial of service condition or the execution of
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.");
