Vulnerability in the Java SE product of Oracle Java SE (component: JSSE).
Supported versions that are affected are Java SE: 11.0.5 and 13.0.1.
Difficult to exploit vulnerability allows unauthenticated attacker with
network access via HTTPS to compromise Java SE. Successful attacks of this
vulnerability can result in unauthorized update, insert or delete access to
some of Java SE accessible data as well as unauthorized read access to a
subset of Java SE accessible data. 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 4.8 (Confidentiality and
Integrity impacts). CVSS Vector:
(CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N).

Bengt Jonsson, Juraj Somorovsky, Kostis Sagonas, Paul Fiterau Brostean and
Robert Merget discovered that OpenJDK incorrectly handled CertificateVerify TLS
handshake messages. A remote attacker could possibly use this issue to insert,
edit or obtain sensitive information. This issue only affected OpenJDK 11.
