Description

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.

Affected configurations

• rabbitmq-c project rabbitmq-c (< 0.10.0) • fedoraproject fedora 30 • fedoraproject fedora 31 • canonical ubuntu linux 14.04 • canonical ubuntu linux 16.04 • canonical ubuntu linux 18.04 • canonical ubuntu linux 19.04 • canonical ubuntu linux 19.10 • debian debian linux 8.0
