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.
