Description Tomas Hoger 2020-04-12 16:02:05 UTC
A flaw was found in the Nashorn JavaScript engine in the Scripting component of OpenJDK.  Processing of the forward references prior to checking for regular expression syntax errors could cause an unexpected exception to be raised when processing a specially crafted regular expression.
