"CVE-2018-2638
8.3
AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H
Supported versions that are affected are Java SE: 8u152 and
9.0.1. 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 and
while the vulnerability is in Java SE, attacks may
significantly impact additional products. Successful attacks
of this vulnerability can result in takeover of Java SE.
Note: This vulnerability applies to Java deployments,
typically in clients running sandboxed Java Web Start
applications or sandboxed Java applets, 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).

MITIGATION
Oracle states:
"Due to the threat posed by a successful attack, Oracle
strongly recommends that customers apply CPU fixes as soon
as possible. Until you apply the CPU fixes, it may be
possible to reduce the risk of successful attack by blocking
network protocols required by an attack. For attacks that
require certain privileges or access to certain packages,
removing the privileges or the ability to access the
packages from users that do not need the privileges may help
reduce the risk of successful attack. Both approaches may
break application functionality, so Oracle strongly
recommends that customers test changes on non-production
systems. Neither approach should be considered a long-term
solution as neither corrects the underlying problem." [1]
