Summary
librabbitmq vulnerabilities
Details
It was discovered that the rabbitmq-c command-line tools only accepted credentials on the command line, making them visible to other local users through the process list. An attacker could possibly use this to obtain sensitive credentials. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, and Ubuntu 20.04 LTS. (CVE-2023-35789)
It was discovered that rabbitmq-c did not correctly compute AMQP frame lengths, leading to a size_t underflow. A remote attacker could possibly use this to cause rabbitmq-c to crash, resulting in a denial of service, or possibly expose sensitive information. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, and Ubuntu 20.04 LTS. (CVE-2026-44235)
It was discovered that rabbitmq-c did not properly validate the frame size during the AMQP login handshake. A remote attacker could possibly use this to cause a heap buffer overflow, resulting in a denial of service or possibly the execution of arbitrary code. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, and Ubuntu 20.04 LTS. (CVE-2026-44236)
It was discovered that rabbitmq-c did not correctly validate the length of decoded bytes fields, leading to an integer overflow in a bounds check on 32-bit systems. A remote attacker controlling a broker, or able to intercept an unencrypted connection, could possibly use this to cause an out-of-bounds read, resulting in a denial of service or the exposure of sensitive information. (CVE-2026-59986)
It was discovered that rabbitmq-c did not validate the body fragment length when serialising an AMQP body frame with the amqp_send_frame() API. An attacker could possibly use this to cause a heap buffer overflow, resulting in a denial of service (application crash) or possibly the execution of arbitrary code. This issue did not affect Ubuntu 14.04 LTS. (CVE-2026-61547)

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.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
