Description Tomas Hoger 2017-01-17 05:25:16 EST
A covert timing channel flaw was found in the DSA implementation in the Libraries component of OpenJDK.  A remote attacker able to make a Java application generate DSA signatures on demand could possibly use this flaw to extract certain information about the used key via a timing side channel.
