CVE-2020-5806
An attacker-controlled memory allocation size can be passed to the C++ new operator in the CServerManager::HandleBrowseLoadIconStreamRequest in messaging.dll.
Does this matter?
Lower severity and a low EPSS score (4.78%). Track it; it rarely justifies an emergency change on its own.

This can be done by sending a specially crafted message to 127.0.0.1:7153. Observed in FactoryTalk Linx 6.11. All versions of FactoryTalk Linx are affected.
