Descrição técnica

Mongoose is an embedded web server and network library. Prior to 7.22, mg_path_is_sane in src/util.c read path.buf[1] without first requiring path.len to be at least two and read s[2] when only two bytes remained. Unauthenticated remote requests reaching mg_http_upload or mg_http_serve_dir with the affected short path shapes could therefore trigger one-byte heap out-of-bounds reads. On bare-metal or RTOS targets without memory protection, the adjacent byte could be exposed or influence whether a path was accepted, and instrumented builds could crash. This issue is fixed in version 7.22.

CVE-2026-734716.1 MÉD

—

———A flaw was found in GStreamer gst-plugins-good (avidemux). In the Nikon metadata tag parser, a pointer can be dereferenced without verifying that data remains in the buffer, causing out-of-bounds reads. Because avidemux is auto-plugged by playbin, decodebin, and gst-discoverer, opening or previewing a crafted AVI is sufficient to trigger the issue. Fixed upstream in gst-plugins-good 1.28.6 (GStreamer-SA-2026-0072).11h CVE-2026-1232693.3 BAI

———A vulnerability was detected in libyal libvmdk. Affected by this vulnerability is the function libvmdk_descriptor_file_read_header of the file libvmdk/libvmdk_descriptor_file.c of the component Descriptor File Parser. The manipulation results in out-of-bounds read. The attack must be initiated from a local position. The exploit is now public and may be used. The patch is identified as 175d3fc0a0b961f362f16e7560a6169d7213e16b. It is best practice to apply a patch to resolve this issue.16h CVE-2026-926988.2 ALT

———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'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.19h CVE-2026-926977.5 ALT

———FastNetMon is a high-performance DDoS detector and sensor. 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.19h CVE-2026-926958.2 ALT

—

———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->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.19h CVE-2026-926938.2 ALT

—

———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.19h
