CVE-2021-2438

Estado: ModificadaMedia (4.3)—

Vulnerability in the Java VM component of Oracle Database Server. Supported versions that are affected are 12.1.0.2, 12.2.0.1 and 19c. Easily exploitable vulnerability allows low privileged attacker having Create Procedure privilege with network access via Oracle Net to compromise Java VM. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java VM. CVSS 3.1 Base Score 4.3 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L).
