The remote Ubuntu 16.04 ESM / 18.04 LTS / 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5004-1 advisory.
It was discovered that RabbitMQ incorrectly handled certain inputs. An attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 16.04 ESM and Ubuntu 18.04 LTS.
(CVE-2019-11287)
Jonathan Knudsen discovered RabbitMQ incorrectly handled certain inputs. An attacker could possibly use this issue to cause a denial of service. (CVE-2021-22116)
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.
