CVE-2018-16758
Missing message authentication in the meta-protocol in Tinc VPN version 1.0.34 and earlier allows a man-in-the-middle attack to disable the encryption of VPN packets.
Does this matter?
Lower severity and a low EPSS score (0.95%). Track it; it rarely justifies an emergency change on its own.
