Description Tomas Hoger 2015-07-10 16:18:53 UTC 
It was discovered that the JCE (Java Cryptography Extension) component in OpenJDK failed to use constant time comparisons in multiple cases.  An attacker could possibly use these flaws to disclose sensitive information by measuring time used to perform operations using these non-constant time comparisons.
Comment 1 Tomas Hoger 2015-07-14 20:40:00 UTC 
Public now via Oracle Critical Patch Update - July 2015.  Fixed in Oracle Java SE 6u101, 7u85, and 8u51.
