UBUNTU-CVE-2026-44235 (CVE-2026-44235)

Vulnerability from osv_ubuntu – Published: 2026-06-11 00:00 – Updated: 2026-09-23 23:29 – Source website

Details

rabbitmq-c is a C-language AMQP client library for RabbitMQ. Prior to 0.16.0, a malicious AMQP server can send an undersized HEADER or METHOD frame during client login and cause unsigned size_t underflow in amqp_handle_input() in librabbitmq/amqp_connection.c. The parser subtracts HEADER_SIZE, fixed per-frame fields, and FOOTER_SIZE from state->target_size without first checking the minimum frame length. The wrapped encoded.len value is passed through amqp_decode_properties() to amqp_decode_table_internal(), where it defeats bounds checks and causes an out-of-bounds read and process crash. An on-path attacker can also trigger the issue when AMQP traffic is not protected by TLS with certificate validation. The demonstrated impact is denial of service, with no reliable memory disclosure or code execution shown. This issue is fixed in version 0.16.0.

          "value": "rabbitmq-c is a C-language AMQP client library for RabbitMQ. Prior to 0.16.0, a malicious AMQP server can send an undersized HEADER or METHOD frame during client login and cause unsigned size_t underflow in amqp_handle_input() in librabbitmq/amqp_connection.c. The parser subtracts HEADER_SIZE, fixed per-frame fields, and FOOTER_SIZE from state-\u003etarget_size without first checking the minimum frame length. The wrapped encoded.len value is passed through amqp_decode_properties() to amqp_decode_table_internal(), where it defeats bounds checks and causes an out-of-bounds read and process crash. An on-path attacker can also trigger the issue when AMQP traffic is not protected by TLS with certificate validation. The demonstrated impact is denial of service, with no reliable memory disclosure or code execution shown. This issue is fixed in version 0.16.0."

USN-8437-1 (UBUNTU-CVE-2023-35789)

Vulnerability from osv_ubuntu – Published: 2026-06-16 14:48 – Updated: 2026-09-21 07:00 – Source website

Summary

librabbitmq vulnerabilities

Details

It was discovered that rabbitmq-c exposed credentials in command-line arguments under certain circumstances. A local attacker could possibly use this issue to obtain sensitive information. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2023-35789)

It was discovered that rabbitmq-c incorrectly handled AMQP frame lengths under certain circumstances, which could lead to an out-of-bounds read. A remote attacker could possibly use this issue to cause rabbitmq-c to crash, resulting in a denial of service. (CVE-2026-44235)

It was discovered that rabbitmq-c incorrectly handled AMQP login handshakes under certain circumstances, which could lead to a heap buffer overflow. A remote attacker could possibly use this issue to cause rabbitmq-c to crash, resulting in a denial of service, or execute arbitrary code. (CVE-2026-44236)

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)
