Descriptions
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 CVE-2019-9848, 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. This issue affects: Document Foundation LibreOffice versions prior to 6.2.6.
LibreOffice está comúnmente incorporada con LibreLogo, un script de gráficos vectoriales turtle programables, lo que puede ejecutar comandos arbitrarios de python contenidos con el documento desde que se inicia. Se agregó protección, para abordar el CVE-2019-9848, para bloquear las llamadas a LibreLogo desde los manejadores de script de eventos de documentos, p.ej. mouse over. Sin embargo, LibreOffice también presenta una funcionalidad separada en la que los documentos pueden especificar que los scripts preinstalados pueden ser ejecutados en varios eventos de script globales, tales como document-open, etc. Este problema afecta: Document Foundation LibreOffice versiones anteriores a 6.2.6.
