CVE-2019-2818

Priority
Description
Vulnerability in the Java SE component of Oracle Java SE (subcomponent:
Security). Supported versions that are affected are Java SE: 11.0.3 and
12.0.1. 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 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
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 (Confidentiality impacts). CVSS Vector:
(CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N).
Ubuntu-Description
It was discovered that the ChaCha20Cipher implementation in OpenJDK
did not use constant time computations in some situations. An attacker
could use this to expose sensitive information.
