BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to versions 1.4.4, 1.5.1, and 1.6.0, a stack-buffer-overflow can be triggered in the current master branch when a Loop object reads a referenced property through its default timer path and the referenced property is OBJECT_STRUCTURED_VIEW / PROP_DESCRIPTION containing a long attacker-controlled string. This issue has been patched in versions 1.4.4, 1.5.1, and 1.6.0.
