ASYNC_ENCRYPT: Race condition in cipher queue usage can cause message decryption failures ----------------------------------------------------------------------------------------- Key: JGRP-2315 URL: https://issues.jboss.org/browse/JGRP-2315 Project: JGroups Issue Type: Bug Affects Versions: 4.0.15 Reporter: Paul Ferraro Assignee: Bela Ban Priority: Major If a message is received that needs to be decrypted, or if a message need to be encrypted, a cipher is taken from the queue. However, if a new coordinator concurrently sends a new secret key, it will clear and recreate the cipher queues. If the previous operation then puts its cipher back on the queue, the queue will now contain a cipher with the old secret key. This will result in random message decryption failures when a message encryption/decryption pulls the outdated cipher from the queue.
