Description Tomas Hoger 2020-01-14 15:18:19 UTC 
It was discovered that the TLS implementation in the Security component of OpenJDK did not correctly handle CertificateVerify TLS handshake message received unexpectedly.  A remote attacker attacker could use this flaw to affect confidentiality or integrity of a TLS connection.
