Description Tomas Hoger 2018-10-16 09:49:46 EDT

It was discovered that the Security component of OpenJDK could incorrectly use unsigned manifest attribute entries when only properly signed entries were meant to be used.  This could lead to bypass of protections provided by Jar signing.  An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions.
