Overview

openjdk-jre is a free and open-source implementation of the Java Platform, Standard Edition (Java SE).

Affected versions of this package are vulnerable to Improper Certificate Validation. A flaw was found in the way the JSSE component of OpenJDK performed TLS server name verification. The HostnameChecker class did not check if names stored in TLS server's X.509 certificate are in the normalized form, possibly leading to an incorrect name being matched.
