Description Tomas Hoger 2019-07-15 21:11:48 UTC
It was discovered that crypto provider implementations in the JCE component of OpenJDK for crypto algorithms such as AES or SHA did not perform array bounds checks.  This could lead to out-of-bounds access if compiler intrinsics were used instead of the Java runtime implementations of the specific operations.
