"value": "BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to versions 1.4.5, 1.5.1, and 1.6.0, the bsc_node_parse_urls() function in src/bacnet/datalink/bsc/bsc-node.c contains three distinct bugs when parsing space-separated WebSocket URIs from a BACnet/SC Address Resolution ACK message. Two bugs cause out-of-bounds writes past the utf8_urls[10][129] array in the static BSC_ADDRESS_RESOLUTION structure. This issue has been patched in versions 1.4.5, 1.5.1, and 1.6.0."
