Description Tomas Hoger 2016-10-18 08:04:12 UTC
A flaw was found in the way the AWT component of OpenJDK running on Microsoft Windows platform handled menus.  An untrusted Java application or applet could use this flaw to bypass Java sandbox restrictions.

Comment 1 Tomas Hoger 2016-10-18 08:06:33 UTC
This flaw only affects OpenJDK versions running on Microsoft Windows.  OpenJDK versions for Linux do not use the affected code and were therefore not affected by this issue.

Comment 2 Tomas Hoger 2016-10-18 20:09:20 UTC
Public now via Oracle CPU October 2016, fixed in Oracle JDK 8u111, 7u121, and 6u131.
