In Mitre's CVE dictionary: CVE-2019-18609.
More information:

It was discovered that there was an integer overflow vulnerability in librabbitmq, a library for robust messaging between applications and servers.

  • CVE-2019-18609

    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.

For Debian 8 Jessie, these problems have been fixed in version 0.5.2-2+deb8u1.

We recommend that you upgrade your librabbitmq packages.
