Edit controls, including Rich Edit controls, are a common type of Windows control found in many applications. They can be embedded directly in the application or as subclassed windows.

When these controls display text in multiline mode, they use a callback function called EditWordBreakProc. This function is called every time the control needs to do something related to word wrapping.

Additionally, when a Rich Edit control receives the EM_STREAMIN message, it uses the information provided in an EDITSTREAM structure to transfer data into or out of the control. The pfnCallback field of this structure can be used to point to a payload in memory, allowing for the injection of malicious code.
