REDHAT-BUG-1298906: Icu layout engine vulnerability

Published Jan 15, 2016

Updated

Integer signedness issues were discovered in IndicRearrangementProcessor and IndicRearrangementProcessor2 in the ICU Layout Engine. 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.
