CVE-2019-9851: LibreLogo global-event script execution
First published: Thu Aug 15 2019(Updated: )
A vulnerability was found in LibreOffice prior to 6.2.6. LibreOffice is typically bundled with LibreLogo, a programmable turtle vector graphics script, which can execute arbitrary python commands contained with the document it is launched from. Protection was added, to address <a href="https://access.redhat.com/security/cve/CVE-2019-9848">CVE-2019-9848</a>, to block calling LibreLogo from document event script handers, e.g. mouse over. However LibreOffice also has a separate feature where documents can specify that pre-installed scripts can be executed on various global script events such as document-open, etc. In the fixed versions, global script event handlers are validated equivalently to document script event handlers.
