Vulnerability in the Java SE, Java SE Embedded component of Oracle Java SE
(subcomponent: Hotspot). Supported versions that are affected are Java SE:
7u191, 8u182 and 11; Java SE Embedded: 8u181. Difficult to exploit
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 and
while the vulnerability is in Java SE, Java SE Embedded, attacks may
significantly impact additional products. Successful attacks of this
vulnerability can result in takeover of Java SE, Java SE Embedded. 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 8.3 (Confidentiality, Integrity and Availability impacts). CVSS
Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H).

It was discovered that the Hotspot component of OpenJDK did not
properly perform access checks in certain cases when performing
field link resolution. An attacker could use this to specially
construct an untrusted Java application or applet that could escape
sandbox restrictions.
