CVE-2020-2778

First published: Tue Apr 14 2020(Updated: )

A flaw was found in the TLS implementation in the JSSE component of OpenJDK. Setting algorithm constraints on SSLParameters using the setAlgorithmConstraints() method could override the systems security policy defined using the jdk.tls.disabledAlgorithms security property and lead to the use of weak algorithms that were intended to be disabled.
