The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5123-2 advisory.
Vulnerability in the MySQL Server product of Oracle MySQL (component: InnoDB). Supported versions that are affected are 5.7.35 and prior and 8.0.26 and prior. Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server as well as unauthorized update, insert or delete access to some of MySQL Server accessible data. CVSS 3.1 Base Score 5.5 (Integrity and Availability impacts). CVSS Vector:
(CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:H). (CVE-2021-35604)
Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Security: Privileges).
Supported versions that are affected are 5.7.35 and prior and 8.0.26 and prior. Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all MySQL Server accessible data. CVSS 3.1 Base Score 4.9 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:N). (CVE-2021-35624)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
