Title: CVE-2019-9848 LibreLogo arbitrary script execution
Announced: July 16, 2019
Fixed in: 6.2.5
Description:
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..
