CVE-2019-2422

Published: 16 January 2019

Vulnerability in the Java SE component of Oracle Java SE (subcomponent: Libraries). Supported versions that are affected are Java SE: 7u201, 8u192 and 11.0.1; Java SE Embedded: 8u191. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Java SE accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets (in Java SE 8), that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). CVSS 3.0 Base Score 3.1 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N).

From the Ubuntu Security Team

It was discovered that a memory disclosure issue existed in the OpenJDK Library subsystem. An attacker could use this to expose sensitive information and possibly bypass Java sandbox restrictions.
