CVE-2018-2582

Published: 17 January 2018

Vulnerability in the Java SE, Java SE Embedded component of Oracle Java SE (subcomponent: Hotspot). Supported versions that are affected are Java SE: 8u152 and 9.0.1; Java SE Embedded: 8u151. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Java SE, Java SE Embedded accessible data. 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 6.5 (Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N).

From the Ubuntu Security Team

It was discovered that the Hotspot component of OpenJDK did not properly validate uses of the invokeinterface JVM instruction. An attacker could possibly use this to access unauthorized resources.
