Description Ganesh 2026-11-13 09:34:23 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

rabbitmq-c is a C-language AMQP client library for RabbitMQ. Prior to version 0.17.0, a heap buffer overflow exists in rabbitmq-c when the public amqp_send_frame() API is used to serialize an oversized AMQP_FRAME_BODY. The issue occurs because amqp_frame_to_bytes() copies frame.payload.body_fragment.len bytes into the connection outbound buffer without validating that the body fragment fits within the allocated frame buffer. An application that passes an oversized body frame to amqp_send_frame() can trigger a heap out-of-bounds write, resulting in process crash and memory corruption. This issue has been patched in version 0.17.0.
