Description Tomas Hoger 2015-10-20 08:21:20 UTC
It was discovered that ICU Layout Engine was missing multiple boundary and error return checks.  These could lead to buffer overflows and memory corruption.  A specially crafted font file could cause an application using ICU to parse untrusted fonts 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 execute arbitrary code with Java Virtual Machine privileges and bypass Java sandbox restrictions.

Comment 1 Tomas Hoger 2015-10-21 08:53:22 UTC
Public now via Oracle Critical Patch Update - October 2015.  Fixed in Oracle Java SE 6u105, 7u91, and 8u65.
