amqp091-go: Pre-negotiation frame limit is not enforced to 4KB

Summary The frame-size mitigation released in amqp091-go v1.13.0 can be bypassed before connection.tune completes. A malicious or compromised AMQP peer can send only a seven-byte body-frame header containing a large attacker-controlled uint32 payload length. The client allocates a slice of that...

CVE-2026-107386

amqp091-go is a Go AMQP 0.9.1 client. From 1.13.0 until 1.14.0, the frame-size mitigation from the prior allocation advisory can be bypassed before connection.tune completes because Connection.maxFrameSize uses zero for both the not-yet-negotiated and negotiated-unlimited states. A malicious or...

rabbitmq-c is a C-language AMQP client library for RabbitMQ. Prior to 0.16.0, a malicious AMQP server can send an undersized connection.tune.frame max value during amqp login, and rabbitmq-c accepts the value in amqp login inner in librabbitmq/amqp socket.c. amqp tune connection in librabbitmq/am...

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with RabbitMQ nodes. Prior to 5.34.0, AMQConnection.start...

DEBIAN-CVE-2026-75516

The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with RabbitMQ nodes. Prior to 5.34.0, AMQConnection.start applies Math.minmaxInboundMessageBodySize, frameMax after Connection.Tune negotiation even though AMQP defines frameMax value zero as...

CVE-2026-75516

The RabbitMQ Java client (versions prior to 5.34.0 ) contains a logic flaw where AMQConnection.start() computes Math.min(maxInboundMessageBodySize, frameMax) after Connection.Tune negotiation. Since both the client default and AMQP's zero-value frameMax resolve to zero, Utils.framePayloadLimit(in...
