Description Tomas Hoger 2021-04-19 20:37:27 UTC

A flaw was found in the way the Libraries component of OpenJDK enforced constraints defined in the jdk.jar.disabledAlgorithms security property.  Verification of a JAR filed signed using a disabled algorithm could succeed in certain cases, leading to bypass of the intended security restrictions.
