Descriptions

The SwCTBWrapper::Read function in sw/source/filter/ww8/ww8toolbar.cxx in LibreOffice before 5.4.6.1 and 6.x before 6.0.2.1 does not validate a customizations index, which allows remote attackers to cause a denial of service (heap-based buffer overflow with write access) or possibly have unspecified other impact via a crafted document that contains a certain Microsoft Word record.

La función SwCTBWrapper::Read en sw/source/filter/ww8/ww8toolbar.cxx en LibreOffice, en versiones anteriores a la 5.4.6.1 y versiones 6.x anteriores a la 6.0.2.1, no valida un índice de personalizaciones. Esto permite que los atacantes remotos provoquen una denegación de servicio (desbordamiento de búfer basado en memoria dinámica o heap con acceso de escritura) o cualquier otro tipo de impacto sin especificar mediante un documento manipulado que contiene un registro de Microsoft Word determinado.
