nDPI through 4.12 has a potential stack-based buffer overflow in ndpiaddresscacherestore in lib/ndpicache.c.

In nDPI through 3.2, the packet parsing code is vulnerable to a heap-based buffer over-read in ndpiparsepacketlineinfo in lib/ndpimain.c.

In nDPI through 3.2, the OpenVPN dissector is vulnerable to a heap-based buffer over-read in ndpisearchopenvpn in lib/protocols/openvpn.c.

The NTOP Deep Packet Inspection Toolkit is driven in large part by the nDPI library. This library contains a large set of network protocol dissectors intended to parse and analyze packet-captured network traffic.

In nDPI through 3.2 Stable, the SSH protocol dissector has multiple KEXINIT integer overflows that result in a controlled remote heap overflow in concathashstring 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.

In nDPI through 3.2 Stable, an out-of-bounds read in concathashstring 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.
