A covert timing channel flaw was found in the DSA implementation in the JCE 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.

Description Tomas Hoger 2017-07-17 14:32:04 UTC 
A covert timing channel flaw was found in the DSA implementation in the JCE 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.

Note that the fix for this issue reverts the fix for CVE-2016-5548 (see bug 1413920) and uses different approach to implement blinding of the DSA operations.
