rabbitmq-server: RabbitMQ is a messaging and streaming broker

RabbitMQ is a messaging and streaming broker. Versions prior to 4.0.3 arevulnerable to a sophisticated attack that could modify virtual host name ondisk and then make it unrecoverable (with other on disk file modifications)can lead to arbitrary JavaScript code execution in the browsers ofmanagement UI users. When a virtual host on a RabbitMQ node fails to start,recent versionswill display an error message (a notification) in the management UI. Theerror message includes virtual host name, which was not escaped prior toopen source RabbitMQ 4.0.3 and Tanzu RabbitMQ 4.0.3, 3.13.8. An attack thatboth makes a virtual host fail to start and creates a new virtual host namewith an XSS code snippet or changes the name of an existing virtual host ondisk could trigger arbitrary JavaScript code execution in the management UI(the user's browser). Open source RabbitMQ `4.0.3` and Tanzu RabbitMQ`4.0.3` and `3.13.8` patch the issue.
