Vulnerability in the Java SE, Java SE Embedded, JRockit component of Oracle Java SE (subcomponent: JNDI). Supported versions that are affected are Java SE: 6u171, 7u161, 8u152 and 9.0.1; Java SE Embedded: 8u151; JRockit: R28.3.16. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded, JRockit. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Java SE, Java SE Embedded, JRockit accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Java SE, Java SE Embedded, JRockit. Note: This vulnerability applies to client and server deployment of Java. This vulnerability can be exploited through sandboxed Java Web Start applications and sandboxed Java applets. It can also be exploited by supplying data to APIs in the specified Component without using sandboxed Java Web Start applications or sandboxed Java applets, such as through a web service. CVSS 3.0 Base Score 4.8 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:L).

From the Ubuntu Security Team

It was discovered that the DNS client implementation in OpenJDK did not properly randomize source ports. A remote attacker could use this to spoof responses to DNS queries made by Java applications.
