Vulnerability details
The vulnerability allows a remote user to terminate the consumer JVM.
The vulnerability exists due to improper input validation in Java deserialization handling when processing a hostile AMQP message containing nested arrays. A remote privileged user can send a specially crafted AMQP message to terminate the consumer JVM.
The default JavaLangErrorHandler invokes System.exit(99) after the resulting StackOverflowError, causing full availability loss for workloads co-located in the same process.
