Description Tomas Hoger 2018-10-24 04:05:28 EDT

A flaw was found in the way the Sound component of OpenJDK handled MIDI sound devices on the Windows platform, possibly leading to the use or exposure of an uninitialized memory.  An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions.

Public via Oracle CPU October 2018:

The issue was fixed in Oracle JDK 11.0.1.

This only affected OpenJDK builds for the Microsoft Windows platform and did not affect Linux builds.
