Description Sam Fowler 2018-04-20 05:16:16 UTC 
LibreOffice before versions 5.4.6.1 and 6.0.2.1 has a missing bounds check in sw/source/filter/ww8/ww8toolbar.cxx:SwCTBWrapper::Read() allowing for an out of bounds write. An attacker could exploit this to cause a denial of service via crafted document.
