Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

GHSA-qx7j-jv8m-fppr affects the RabbitMQ Java client package com.rabbitmq:amqp-client before 5.31.0. A malicious or compromised broker peer that the client has connected to can send a content header declaring a small body followed by a larger body frame, causing an unhandled exception that tears down the client connection, a denial of service. The source states that no memory corruption, data disclosure, or code execution is indicated. Upgrade to version 5.31.0 or later.
