In version 1.2.9 and earlier, the NetFlow v9 collector calls strlen() on an attacker-controlled interface-description field without bounding the scan to the field’s declared length. Although fields longer than 128 bytes are excluded from this operation, an accepted field without a null terminator can cause reads beyond the field and packet buffer. An unauthenticated remote attacker who can send crafted UDP packets to the collector can trigger an out-of-bounds read and potentially crash the process, causing denial of service. No fixed release is available as of this review.</description></item><item><title>CVE-2026-92698: FastNetMon: sFlow header_size field trusted as parser capture length causes remote out-of-bounds read</title><link>https://vulnfeed.org/cve/CVE-2026-92698/</link><guid isPermaLink="true">https://vulnfeed.org/cve/CVE-2026-92698/</guid><pubDate>Thu, 05 Nov 2026 23:17:02 +0000</pubDate><description>FastNetMon is a high-performance DDoS detector and sensor. In version 1.2.9 and earlier, process_sflow_flow_sample() in src/sflow_plugin/sflow_collector.cpp passes the attacker-controlled sflow_raw_protocol_header_t.header_size to parse_raw_packet_to_simple_packet_full() as its trusted captured length without comparing it with the bytes remaining in the record. An inflated header_size creates a false end pointer beyond the received sFlow v5 UDP buffer, defeating the nested parser&apos;s bounds checks and causing an unauthenticated remote out-of-bounds read and process crash, with possible limited exposure of adjacent bytes through parsed flow fields. No fixed release is available as of this review.</description></item><item><title>CVE-2026-93424: FastNetMon: NetFlow/IPFIX template cache returns unlocked pointers, causing heap-use-after-free on multi-port deployments</title><link>https://vulnfeed.org/cve/CVE-2026-93424/</link><guid isPermaLink="true">https://vulnfeed.org/cve/CVE-2026-93424/</guid><pubDate>Thu, 05 Nov 2026 23:17:02 +0000</pubDate><description>FastNetMon is a high-performance DDoS detector and sensor. In version 1.2.9 and earlier, peer_find_template() in src/netflow_plugin/netflow_collector.cpp and src/netflow_plugin/netflow_v9_collector.cpp returns a pointer into global_netflow9_templates after releasing the cache mutex. On deployments with at least two entries in netflow_ports, concurrent template redefinition and data-flowset processing can let add_update_peer_template() reassign the template and free its records vector while another listener dereferences the escaped pointer. An unauthenticated sender that can reach both NetFlow/IPFIX listener ports can trigger a heap-use-after-free and reliably crash FastNetMon. No fixed release is available as of this review.</description></item><item><title>CVE-2026-92693: FastNetMon: IPv6 Fragment header dereferenced without bounds check in shared packet parser</title><link>https://vulnfeed.org/cve/CVE-2026-92693/</link><guid isPermaLink="true">https://vulnfeed.org/cve/CVE-2026-92693/</guid><pubDate>Thu, 05 Nov 2026 23:17:01 +0000</pubDate><description>FastNetMon is a high-performance DDoS detector and sensor. In version 1.2.9 and earlier, parse_raw_packet_to_simple_packet_full() in src/simple_packet_parser_ng.cpp dereferences ipv6_extension_header_fragment_t when IpProtocolNumberIPV6_FRAG is present without first verifying that the eight-byte Fragment header remains. A crafted sFlow v5 RAW_PACKET_HEADER record can remotely reach this shared parser with the Fragment bytes omitted, causing an unauthenticated remote out-of-bounds read. The supplied harness detects the read under AddressSanitizer, but the advisory does not establish a production process crash. No fixed release is available as of this review.</description></item><item><title>CVE-2026-92695: FastNetMon: Legacy pcap parse_packet() has no bounds checking, causing out-of-bounds read on truncated frames</title><link>https://vulnfeed.org/cve/CVE-2026-92695/</link><guid isPermaLink="true">https://vulnfeed.org/cve/CVE-2026-92695/</guid><pubDate>Thu, 05 Nov 2026 22:30:59 +0000</pubDate><description>FastNetMon is a high-performance DDoS detector and sensor. In version 1.2.9 and earlier, the live parse_packet() callback in src/pcap_plugin/pcap_collector.cpp is registered through pcap_loop and processes captured frames when pcap = on without checking packethdr-&gt;caplen. A short frame or an attacker-controlled IPv4 header length can make the parser dereference IP or transport headers beyond the captured bytes, causing an out-of-bounds read and process termination. No fixed release is available as of this review.</description></item></channel></rss>
