ntop nDPI through 6.0 contains an out-of-bounds read vulnerability in dissect_softether_host_fqdn() in softether.c that compares host_name using the consumed byte count instead of data length. Remote attackers can send crafted short UDP datagrams on already-classified SoftEther flows, causing strncmp to read beyond the packet payload buffer.
nDPI 5.1.0 contains a memory access issue in the DNS dissector and serializer deserialization code. Specially crafted network input can cause byte-buffer addresses at odd offsets to be cast to uint16_t or wider integer pointers and directly dereferenced without alignment checks. This results in undefined behavior and can cause process termination in UBSan-instrumented builds or on strict-alignment architectures, leading to denial of service.
ntop nDPI versions before 6.0 contain a heap buffer overflow vulnerability in the ndpi_json_string_escape function that writes beyond caller-supplied buffer boundaries. Attackers can trigger the overflow by supplying crafted network packet data including TLS SNI, HTTP headers, or DNS names that reach the vulnerable function, causing heap corruption.
ntop nDPI 3.4 has a stack-based buffer overflow in processClientServerHello.
In nDPI through 3.2, the packet parsing code is vulnerable to a heap-based buffer over-read in ndpi_parse_packet_line_info in lib/ndpi_main.c.
In nDPI through 3.2, the H.323 dissector is vulnerable to a heap-based buffer over-read in ndpi_search_h323 in lib/protocols/h323.c, as demonstrated by a payload packet length that is too short.
In nDPI through 3.2, the OpenVPN dissector is vulnerable to a heap-based buffer over-read in ndpi_search_openvpn in lib/protocols/openvpn.c.
In nDPI through 3.2, there is a stack overflow in extractRDNSequence in lib/protocols/tls.c.
In nDPI through 3.2, ndpi_reset_packet_line_info in lib/ndpi_main.c omits certain reinitialization, leading to a use-after-free.
In nDPI through 3.2, the Oracle protocol dissector has a heap-based buffer over-read in ndpi_search_oracle in lib/protocols/oracle.c.
In nDPI through 3.2 Stable, an out-of-bounds read in concat_hash_string in ssh.c can be exploited by a network-positioned attacker that can send malformed SSH protocol messages on a network segment monitored by nDPI's library.
In nDPI through 3.2 Stable, the SSH protocol dissector has multiple KEXINIT integer overflows that result in a controlled remote heap overflow in concat_hash_string in ssh.c. Due to the granular nature of the overflow primitive and the ability to control both the contents and layout of the nDPI library's heap memory through remote input, this vulnerability may be abused to achieve full Remote Code Execution against any network inspection stack that is linked against nDPI and uses it to perform network traffic analysis.
