Title
MQTT-C Heap Out-of-Bounds Read and Integer Underflow in mqtt_unpack_publish_response()
Summary
LiamBindle MQTT-C through version 1.1.6 contains a heap-based out-of-bounds read and integer underflow in the mqtt_unpack_publish_response function in src/mqtt.c that allows a remote unauthenticated attacker controlling an MQTT broker - or able to inject MQTT traffic into an unencrypted session - to crash a subscribed MQTT-C client and potentially disclose adjacent heap memory by sending a single crafted PUBLISH packet.

The function performs only a \u0027remaining_length \u003e= 4\u0027 fixed-header sanity check (mqtt.c:1349) and then trusts the broker-controlled 16-bit topic_name_size field at mqtt.c:1354 both as a pointer offset (mqtt.c:1357) and as a subtrahend in the unsigned application_message_size computation (mqtt.c:1367/1369). The last commit to LiamBindle/MQTT-C on master is dated 2022-10-27; the project appears unmaintained and no upstream fix is available. defaultStatus is \u0027unknown\u0027 pending vendor confirmation. CVSS 4.0 is scored 8.7 HIGH and CVSS 3.1 is scored 8.2 HIGH, treating the OOB read as VC:L/C:L (limited heap-byte disclosure subject to allocator layout, often masked by the immediately following crash) and the integer-underflow-driven memmove() crash as VA:H/A:H. Mitigation guidance for downstream consumers: validate topic_name_size + 2 + (qos_level \u003e 0 ? 2 : 0) \u003c= remaining_length before using topic_name_size as a pointer offset or as a subtrahend, or migrate to a maintained MQTT client library (e.g. Eclipse Paho MQTT C, libmosquitto).",

Title
GoPacket's Diameter AVP decoder: uint32 underflow on vendor header size leads to unbounded ~4 GiB allocation (unauthenticated remote DoS)
Summary
gopacket provides packet processing capabilities for Go. In version 1.6.0 and earlier, the Diameter AVP decoder computes an AVP data length by subtracting a fixed header size from an attacker-controlled AVP Length field, so a vendor-flagged AVP whose Length is smaller than the 12-byte header underflows the unsigned 32-bit value and drives an unbounded allocation of roughly 4 GiB, and two such messages in succession OOM-kill a collector, causing an unauthenticated remote denial of service. This issue is fixed in version 1.6.1.

Title
Xcitium Client Security / Comodo Internet Security Remote Denial of Service
Summary
Xcitium Client Security (XCS) before 13.8.2.10019 and Comodo Internet Security (CIS) through 12.3.4.8162 (fix expected by 2026 Q3) contain an integer underflow vulnerability in the firewall driver Inspect.sys that allows remote unauthenticated attackers to crash the system by sending a crafted IPv6 packet with a declared payload length smaller than the sum of its extension-header lengths. The unsigned 64-bit payload-length value underflows to a near-maximal integer, triggering an out-of-bounds read and oversized memcpy in the Windows kernel at DISPATCH_LEVEL, resulting in a blue screen of death even on hosts with all ports blocked.

"value": "Xcitium Client Security (XCS) before 13.8.2.10019 and Comodo Internet Security (CIS) through 12.3.4.8162 (fix expected by 2026 Q3) contain an integer underflow vulnerability in the firewall driver Inspect.sys that allows remote unauthenticated attackers to crash the system by sending a crafted IPv6 packet with a declared payload length smaller than the sum of its extension-header lengths. The unsigned 64-bit payload-length value underflows to a near-maximal integer, triggering an out-of-bounds read and oversized memcpy in the Windows kernel at DISPATCH_LEVEL, resulting in a blue screen of death even on hosts with all ports blocked."

Title
Capstone M68K and RISCV `cs_insn_name()` invalid IDs can trigger out-of-bounds reads and process crashes
Summary
Capstone is a disassembly framework. Prior to version 6.0.0-Alpha9, Capstone's public `cs_insn_name()` API forwards caller-supplied instruction IDs directly to the selected architecture backend. Most backends validate the ID before indexing instruction-name tables, but the M68K and RISCV backends have missing or incomplete bounds checks. On a Capstone handle opened for M68K or RISCV, a caller-controlled invalid instruction ID can trigger an out-of-bounds read and crash the process. The demonstrated impact is availability loss in applications or bindings that expose instruction-name lookup to untrusted IDs. No code execution or data disclosure was demonstrated. Version 6.0.0-Alpha9 patches the issue.
