CVE-2018-16115

https://notcve.org/view.php?id=CVE-2018-16115

Lightbend Akka 2.5.x before 2.5.16 allows message disclosure and modification because of an RNG error. A random number generator is used in Akka Remoting for TLS (both classic and Artery Remoting). Akka allows configuration of custom random number generators. For historical reasons, Akka included the AES128CounterSecureRNG and AES256CounterSecureRNG random number generators. The implementations had a bug that caused the generated numbers to be repeated after only a few bytes. • https://doc.akka.io/docs/akka/current/security/2018-08-29-aes-rng.html • CWE-338: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) •
