## Description

Vulnerability in the Java SE component of Oracle Java SE (subcomponent:
Libraries). The supported version that is affected is Java SE: 10.
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). 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).

### From the Ubuntu Security Team

It was discovered that OpenJDK did not properly validate types in
some situations. An attacker could use this to construct a Java
class that could possibly bypass sandbox restrictions.
