spring-amqp is vulnerable to Deserialization of Untrusted Data
66
Medium Risk
This Affects:
spring-amqpTL;DR
spring-amqp allow-listed Java deserialization can be bypassed with a nested-array payload that triggers StackOverflowError. The default JavaLangErrorHandler then calls System.exit(99) and terminates the whole JVM. A single hostile AMQP message can therefore stop every workload in that process. The patch rejects the nested-array bypass and no longer exits the JVM on that error path.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and the AMQP consumer deserializes Java payloads and uses the default JavaLangErrorHandler.
Background info
spring-amqp is vulnerable to Deserialization of Untrusted Data in versions 0.0.1 - 4.0.4 and 4.1.0 - 4.1.0.
How to fix this
Upgrade the org.springframework.amqp:spring-amqp library to the patch version.
