Description Tomas Hoger 2017-04-18 09:36:35 UTC
A untrusted library search path flaw was found in the JCE (Java Cryptography Extension) component of OpenJDK, caused by a problem with the handling of paths to extension directories in the sun.misc.Launcher class.  A local attacker could possibly use this flaw to cause a Java application using JCE to load an attacker-controlled library and therefore escalate their privileges.
