Details

An issue was discovered in amqphandleinput in amqpconnection.c in rabbitmq-c 0.9.0. There is an integer overflow that leads to heap memory corruption in the handling of CONNECTIONSTATEHEADER. A rogue server could return a malicious frame header that leads to a smaller targetsize value than needed. This condition is then carried on to a memcpy function that copies too much data into a heap buffer.
