Passing a negative integer to Go's built-in make() function for slice allocation triggers an unrecoverable runtime panic (panic: len out of range).\n\nBecause the reader goroutine handles network I/O without an explicit recover() wrapper, this panic propagates up to the runtime root, abruptly terminating the host application.\n\n**Attack Vector / Exploitation Scenario**\nAn attacker capable of spoofing, compromising, or controlling an AMQP broker can exploit this flaw during two primary phases:\n\n1. Connection Establishment: Sending a malicious connection.start handshake frame containing server-properties with an 'x' type field assigned a negative length.\n2. Message Delivery: Delivering a message payload where the header table contains a malformed field matching the criteria above.\n\n**Impact**\nAvailability: High. A single malformed frame can reliably crash the client process, resulting in a persistent Denial of Service (DoS) if the client automatically reconnects and receives the same payload.","status":"published","published":"2026-09-17T17:04:29Z","modified":"2026-09-17T17:04:31Z","cvss":[{"version":"4.0","score":8.9,"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:H","level":"high"}],"cwes":["CWE-681"],"updated_at":"2026-11-02T14:41:18.357514Z"}],"nvd":[{"id":"CVE-2026-77412","description":"RabbitMQ amqp091-go is a Go AMQP 0.9.1 client.

Passing a negative integer to Go's built-in make() function for slice allocation triggers an unrecoverable runtime panic (panic: len out of range).\n\nBecause the reader goroutine handles network I/O without an explicit recover() wrapper, this panic propagates up to the runtime root, abruptly terminating the host application.\n\n**Attack Vector / Exploitation Scenario**\nAn attacker capable of spoofing, compromising, or controlling an AMQP broker can exploit this flaw during two primary phases:\n\n1. Connection Establishment: Sending a malicious connection.start handshake frame containing server-properties with an 'x' type field assigned a negative length.\n2. Message Delivery: Delivering a message payload where the header table contains a malformed field matching the criteria above.\n\n**Impact**\nAvailability: High. A single malformed frame can reliably crash the client process, resulting in a persistent Denial of Service (DoS) if the client automatically reconnects and receives the same payload.","status":"published","published":"2026-09-17T17:04:29Z","modified":"2026-10-01T20:55:54.975644527Z","cvss":[{"version":"4.0","score":8.9,"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:H","level":"high"}],"cwes":["CWE-681"],"updated_at":"2026-11-02T15:46:37.528068Z"},{"id":"RHSA-2026:68290","title":"Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update","status":"published","published":"2026-09-22T10:19:11Z","modified":"2026-10-20T10:43:37.203533689Z","cvss":[{"version":"3.1","score":8.8,"vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","level":"high"}],"updated_at":"2026-11-02T15:53:22.406388Z"},{"id":"UBUNTU-CVE-2026-77412","description":"RabbitMQ amqp091-go is a Go AMQP 0.9.1 client.
