Description Tomas Hoger 2020-10-20 11:56:00 UTC
It was discovered that the Libraries component of OpenJDK failed to perform permission check when converting file system paths to URI in UnixUriUtils and WindowsUriSupport classes.  An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions.
