Technical details
The shared GZIP decompressor in Qpid Broker-J lacks a decompressed-output limit when processing AMQP 0-8/0-9/0-9-1 and AMQP 0-10 messages during message delivery, conversion, and HTTP management JSON rendering. An authenticated message producer can exploit this by sending compressed payloads that decompress to extremely large sizes, exhausting broker memory and causing denial of service. The vulnerability requires authentication to exploit.
