CVE-2018-10238 is a critical buffer overflow vulnerability affecting the BACnet Protocol Stack (bacserv) versions 0.9.1 and 0.8.5. The flaw, residing in the bvlc.c component, stems from insufficient packet-size validation during the forwarding of BACnet/IP NPDUs, leading to a stack-based buffer overflow that can clobber stack canaries. With a CVSS score of 9.8, this vulnerability is easily exploitable over the network without authentication, allowing for complete compromise of confidentiality, integrity, and availability. While no public exploit code or active exploitation has been observed, and community discussion is minimal, the high severity warrants immediate patching to version 0.8.6.
