VLAI
Summary
BACnet Protocol Stack through 0.8.6 has a segmentation fault leading to denial of service in BACnet APDU Layer because a malformed DCC in AtomicWriteFile, AtomicReadFile and DeviceCommunicationControl services. An unauthenticated remote attacker could cause a denial of service (bacserv daemon crash) because there is an invalid read in bacdcode.c during parsing of alarm tag numbers.

CVE-2018-10238 (GCVE-0-2018-10238)
Vulnerability from cvelistv5 – Published: 2018-04-20 07:00 – Updated: 2024-08-05 07:32
VLAI
Summary
bvlc.c in skarg BACnet Protocol Stack bacserv 0.9.1 and 0.8.5 is affected by a Buffer Overflow because of a lack of packet-size validation. The affected component is bacserv BACnet/IP BVLC forwarded NPDU. The function bvlc_bdt_forward_npdu() calls bvlc_encode_forwarded_npdu() which copies the content from the request into a local in the bvlc_bdt_forward_npdu() stack frame and clobbers the canary. The attack vector is: A BACnet/IP device with BBMD enabled based on this library connected to IP network. The fixed version is: 0.8.6.
