Description Tomas Hoger 2021-10-18 21:04:04 UTC

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.
