Double free issue exists in Kostac PLC Programming Software Version 1.6.11.0 and earlier. Arbitrary code may be executed by having a user open a specially crafted project file which was saved using Kostac PLC Programming Software Version 1.6.9.0 and earlier because the issue exists in parsing of KPP project files.
