Overview
Affected versions of this package are vulnerable to Heap-based Buffer Overflow in the amqp_login process when an undersized connection.tune.frame_max value is accepted and used to reallocate the outbound buffer without enforcing minimum size constraints. An attacker can cause memory corruption and potentially achieve denial of service or code execution by sending a crafted AMQP handshake from a malicious server or as an on-path attacker against plaintext AMQP traffic.
