CVE-2026-44235

A flaw was found in rabbitmq-c, a C-language AMQP Advanced Message Queuing Protocol client library. A malicious AMQP server or an on-path attacker can send an undersized HEADER or METHOD frame during client login, leading to an unsigned sizet underflow. This underflow causes an out-of-bounds read...
