CVE-2020-11940
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.32%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
