Integer Overflow Vulnerability in RabbitMQ-C Library

CVE-2019-18609

What is CVE-2019-18609?

The rabbitmq-c library version 0.9.0 is susceptible to an integer overflow that can cause heap memory corruption in the function amqp_handle_input. When a malicious server sends a crafted frame header, it can potentially manipulate the target_size value to be smaller than necessary. Consequently, this leads to an unsafe memory copy operation performed by the memcpy function, which can compromise the integrity of the application. Proper validation and checks are critical to mitigate such vulnerabilities.
