CVE-2019-2945

Priority
Description
Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE
(component: Networking). Supported versions that are affected are Java SE:
7u231, 8u221, 11.0.4 and 13; Java SE Embedded: 8u221. 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.
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 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).
Ubuntu-Description
It was discovered that the Socket implementation in OpenJDK did not
properly restrict the creation of subclasses with a custom Socket
implementation. An attacker could use this to specially create a
Java class that could possibly bypass Java sandbox restrictions.
