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 Timing Attack. It was discovered that the TLS implementation in the JSSE component of OpenJDK used non-constant comparisons when checking various data (such as session identifiers or verification data blocks) during TLS handshakes. A malicious TLS client could possibly use this flaw to recover that data by observing timing differences in processing of various inputs.
