## Description

Vulnerability in the Java SE component of Oracle Java SE (subcomponent:
Deployment). The supported version that is affected is Java SE: 8u192.
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.
Successful attacks of this vulnerability can result in unauthorized ability
to cause a partial denial of service (partial DOS) of Java SE. 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 3.1 (Availability impacts). CVSS Vector:
(CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L).
