Description Tomas Hoger 2015-07-13 11:06:56 UTC
It was discovered that ICU Layout Engine was missing multiple boundary checks.  These could lead to buffer overflows and JVM memory corruption.  A specially crafted file could cause an application using ICU to parse untrusted font files to crash and, possibly, execute arbitrary code.

ICU code is embedded the 2D component in OpenJDK and used by FontManager.  An untrusted Java application or applet could use this flaw to bypass Java sandbox restrictions.

Public now via Oracle Critical Patch Update - July 2015.  Fixed in Oracle Java SE 6u101, 7u85, and 8u51.
