Vulnerability in the Java SE, Java SE Embedded component of Oracle Java SE
(subcomponent: Security). Supported versions that are affected are Java SE:
6u201, 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 unauthorized update, insert or delete access to
some of 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). CVSS 3.0 Base Score 3.4
(Integrity impacts). CVSS Vector:
(CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:C/C:N/I:L/A:N).

It was discovered that the Security component of OpenJDK did not
properly ensure that manifest elements were signed before use.
An attacker could possibly use this to specially construct an
untrusted Java application or applet that could escape sandbox
restrictions.
