CVE-2016-2335

Estado: ModificadaAlta (8.8)—

El método CInArchive::ReadFileItem en Archive/Udf/UdfIn.cpp en 7zip 9.20 y 15.05 beta y p7zip permite a atacantes remotos provocar una denegación de servicio (lectura fuera de rango) o ejecutar código arbitrario a través de un archivo PartitionRef en Long Allocation Descriptor en un archivo UDF.
