Ubuntu 22.04 LTS / 24.04 LTS / 25.10 / 26.04 LTS : rabbitmq-c vulnerabilities (USN-8437-1)

medium Nessus Plugin ID 321367

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.10 / 26.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8437-1 advisory.

 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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected amqp-tools, librabbitmq-dev and / or librabbitmq4 packages.
