SCA: security update for com.typesafe.akka:akka-actor_2.11, com.typesafe.akka:akka-actor_2.12 (GHSA-mr95-9rr4-668f)

critical Tenable Self-Hosted Container Security Plugin ID 423071

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. The custom RNG implementations
 were not configured by default but examples in the documentation showed (and therefore implicitly
 recommended) using the custom ones. This can be used by an attacker to compromise the communication if
 these random number generators are enabled in configuration. It would be possible to eavesdrop, replay, or
 modify the messages sent with Akka Remoting/Cluster. (CVE-2018-16115)
