Memory Allocation with Excessive Size Value

Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value which allows a malicious unauthenticated client to allocate large amounts of memory on brokers.


  1. This vulnerability was actually fixed in 3.2.2, but due to an unrelated major bug in this release, we recommend users upgrade to 3.2.3.

  2. The fixed code exists in two components, which means that clients and generator were both affected.
