CVE-2020-11939

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.
