Title

RabbitMQ amqp091-go: Denial of Service via Malicious Field Length in AMQP Client

Summary

RabbitMQ amqp091-go is a Go AMQP 0.9.1 client. Prior to 1.13.0, readField in read.go reads the length of an AMQP byte-array field with type tag x into a signed int32 and passes the value directly to make when allocating the field buffer. A malicious or compromised broker can encode a value such as 0xFFFFFFFF, which becomes -1 and causes a len out of range runtime panic. The panic escapes the network reader goroutine and terminates the client process, including during connection.start server properties or message header table parsing. This issue is fixed in version 1.13.0.

Severity

Vulnerability from csaf_redhat - Published: 2026-10-07 15:14 - Updated: 2026-11-13 13:38

Summary

Red Hat Security Advisory: Red Hat Quay 3.9.27

Severity

Important

Scope

15 vulnerabilities in this advisory, including CVE-2026-77412.

CVE-2026-77412

A flaw was found in RabbitMQ amqp091-go. A malicious or compromised broker can send a specially crafted AMQP (Advanced Message Queuing Protocol) message with a malformed field length. This can cause an integer overflow, leading to a runtime panic in the client process. Consequently, the client process terminates, resulting in a denial of service.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
