Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE
(component: Networking). Supported versions that are affected are Java SE:
7u241 and 8u231; Java SE Embedded: 8u231. Difficult to exploit
vulnerability allows unauthenticated attacker with network access via
multiple protocols to compromise Java SE, Java SE Embedded. Successful
attacks of this vulnerability can result in unauthorized ability to cause a
partial denial of service (partial DOS) 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
can also be exploited by using APIs in the specified Component, e.g.,
through a web service which supplies data to the APIs. CVSS 3.0 Base Score
3.7 (Availability impacts). CVSS Vector:
(CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L).

It was discovered that OpenJDK incorrectly enforced the limit of datagram
sockets that can be created by a code running within Java sandbox. An attacker
could possibly use this issue to bypass the sandbox restrictions causing a
denial of service. This issue only affected OpenJDK 8.
