CVE-2019-9848

LibreOffice has a feature where documents can specify that pre-installed
scripts can be executed on various document events such as mouse-over, etc.
LibreOffice is typically also bundled with LibreLogo, a programmable turtle
vector graphics script, which can be manipulated into executing arbitrary
python commands. By using the document event feature to trigger LibreLogo
to execute python contained within a document a malicious document could be
constructed which would execute arbitrary python commands silently without
warning. In the fixed versions, LibreLogo cannot be called from a document
event handler. This issue affects: Document Foundation LibreOffice versions
prior to 6.2.5.
