## Description

Vulnerability in the Java SE, Java SE Embedded component of Oracle Java SE
(subcomponent: Serviceability). Supported versions that are affected are
Java SE: 8u182 and 11; Java SE Embedded: 8u181. Easily exploitable
vulnerability allows low privileged attacker with logon to the
infrastructure where Java SE, Java SE Embedded executes 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 as well as
unauthorized access to critical data or complete access to all Java SE,
Java SE Embedded 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). This vulnerability can only be
exploited when Java Usage Tracker functionality is being used. CVSS 3.0
Base Score 6.6 (Confidentiality and Integrity impacts). CVSS Vector:
(CVSS:3.0/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N).

### From the Ubuntu Security Team

Nelson William Gamazo Sanchez discovered an unspecified vulnerability
in OpenJDK when the Java Usage Tracker is used. An attacker could
use this to specially construct an untrusted Java application or
applet that could escape sandbox restrictions.
