Summary
An attacker-controlled memory allocation size can be passed to the C++ new operator in RnaDaSvr.dll by sending a specially crafted ConfigureItems message to TCP port 4241. This will cause an unhandled exception, resulting in termination of RSLinxNG.exe. Observed in FactoryTalk 6.11. All versions of FactoryTalk Linx are affected.
