This had to do with the way we exchanged -keys. Since then, we have been working on a new authentication scheme to make -tinc as secure as possible. The current version uses the OpenSSL library and -uses strong authentication with RSA keys. - -On the 29th of December 2001, Jerome Etienne posted a security analysis of tinc -1.0pre4. Due to a lack of sequence numbers and a message authentication code -for each packet, an attacker could possibly disrupt certain network services or -launch a denial of service attack by replaying intercepted packets. The current -version adds sequence numbers and message authentication codes to prevent such -attacks. - -On September the 15th of 2003, Peter Gutmann contacted us and showed us a -writeup describing various security issues in several VPN daemons. He showed -that tinc lacks perfect forward security, the connection authentication could -be done more properly, that the sequence number we use as an IV is not the best -practice and that the default length of the HMAC for packets is too short in -his opinion. We do not know of a way to exploit these weaknesses, but these -issues are being addressed in the tinc 1.1 branch. - -The Sweet32 attack affects versions of tinc prior to 1.0.30. - -On September 6th, 2018, Michael Yonly contacted us and provided -proof-of-concept code that allowed a remote attacker to create an -authenticated, one-way connection with a node, and also that there was a -possibility for a man-in-the-middle to force UDP packets from a node to be sent -in plaintext. The first issue was trivial to exploit on tinc versions prior to -1.0.30, but the changes in 1.0.30 to mitigate the Sweet32 attack made this -weakness much harder to exploit. These issues have been fixed in tinc 1.0.35. -The new protocol in the tinc 1.1 branch is not susceptible to these issues. - -Cryptography is a hard thing to get right. We cannot make any -guarantees.

Compatibility ------------- -Version 1.0.35 is compatible with 1.0pre8, 1.0 and later, but not with older -versions of tinc.
