Description Tomas Hoger 2017-07-18 20:12:18 UTC 
A covert timing channel flaw was found in the ECDSA implementation in the JCE component of OpenJDK.  A remote attacker able to make a Java application generate ECDSA signatures on demand could possibly use this flaw to extract certain information about the used key via a timing side channel.
