Exodus Intelligence claims to have found zero-day vulnerability in the way I2P handles network traffic that can be exploited with the help of a specially configured server. The vulnerability works on default, fully patched installation of Tails. No settings or configurations need to be changed for the exploit to work. Exodus Intelligence is working with the Tails and I2p coders to get the patch soon and after that it won’t charge any fees for disclosing the flaw with more bugs. The number of affected Tails users is not known, but Exodus Intelligence says it will not disclose details to users until the problem has been fixed.
