"The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has librabbitmq packages installed that are
affected by a vulnerability:

  - An issue was discovered in amqp_handle_input in amqp_connection.c in rabbitmq-c 0.9.0. There is an integer
    overflow that leads to heap memory corruption in the handling of CONNECTION_STATE_HEADER. A rogue server
    could return a malicious frame header that leads to a smaller target_size value than needed. This
    condition is then carried on to a memcpy function that copies too much data into a heap buffer.
    (CVE-2019-18609)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
