- Summary
- BACnet Stack: MS/TP COBS decode overflow
- Details
-
BACnet Stack is a BACnet open source protocol stack C library for embedded systems. From versions 1.4.0 to before 1.4.6, 1.5.0 to before 1.5.1, and 1.6.0 to before 1.6.1, the BACnet MS/TP receive path decodes COBS frames into an output pointer inside the same fixed input buffer, but passes the full input-buffer size as the decode capacity. A long valid COBS payload can therefore write past the end of the actual remaining buffer. This issue has been patched in versions 1.4.6, 1.5.1, 1.6.1, and 1.7.0.
